MEMOIRS OF DECEASED MEMBERS.


=LINUS WEED BROWN, M. Am. Soc. C.E.[1]=

DIED MARCH 7TH, 1910.

In the death of Linus Weed Brown, which occurred in Monrovia, Cal., on
March 7th, 1910, this Society lost one of its valued members and the
Engineering Profession a most able exponent.

Mr. Brown was born in Burnside, Orange County, N.Y., in August, 1856,
and received his early education in the schools of that town. He
studied his profession in the Stevens Institute of Technology, Hoboken,
N.J.

At the age of eighteen he entered the machine shops of the Pennsylvania
Railroad, and later was employed as Draftsman by that Company, which
position he held until 1880.

In 1880 he accepted a position with the Southern Pacific Railroad in
New Orleans, La., and designed and supervised the construction of the
Algiers shops.

In 1883 Mr. Brown severed his connection with the Southern Pacific
Company and engaged in general engineering practice, principally in the
line of sugar-house installations.

In 1885 he was elected Assistant City Engineer of New Orleans, which
position he held for four years.

In 1890 he became Chief Engineer for the Caffrey Central Sugar
Refinery, designing and supervising the erection of the buildings,
which represented an expenditure of about $600,000. In the same year
Mr. Brown was appointed Chief Engineer of the Franklin and Abbeville
Railroad and built that road. At the same time he designed and built
the Des Lignes sugar-house. In fact, he designed and built many of the
large sugar mills and refineries erected in Louisiana about that time.

From 1892 to 1896 Mr. Brown held the office of City Engineer of New
Orleans, and it was during this term that some of the most important
works of his career were accomplished.

Under the direction of the City Council, and in consultation with B.M.
Harrod, Past-President, Am. Soc. C.E., the late H.B. Richardson, M.
Am. Soc. C.E., and Rudolph Hering, M. Am. Soc. C.E., Mr. Brown made
a topographical survey of New Orleans, a study of precipitation and
run-off, and prepared plans and specifications for a drainage system.

At the expiration of his term of office as City Engineer, he engaged
in private practice, assuming charge, as Chief Engineer for the
contractors, of the first construction work of the drainage system.

Prior to and during his term of office as City Engineer, Mr. Brown was
Architect of the McDonogh School Fund in New Orleans, during which time
he designed and built several new schools and remodeled a number of old
buildings.

He was also Special Engineer for the New Orleans Levee Board on harbor
and bank protection work. To the study of this work Mr. Brown devoted
all his energies and knowledge for several years. At the same time he
was a member of the New Orleans Advisory Board of Engineers on Sewerage
and Water.

When the oil fields of Texas were first discovered, Mr. Brown's
services were immediately engaged, and in the following years he
devoted almost his entire time to the development of the oil fields and
facilities for handling the oil. His operations were principally in the
Beaumont and Sour Lake fields.

The holdings of the Southern Pacific Railroad Company in these regions
demanded the services of an expert engineer, and Mr. Brown was engaged
to take full charge of its interests.

In 1904 he was compelled to give up active business and seek the
restoration of his health. To this end he spent some time in the Middle
Western States and finally decided to go out to the Pacific Coast.
The climate there proved so beneficial that he eventually settled in
Bakersfield, Cal., where he accepted an appointment as Consulting
Engineer for the Oil Department of the Southern Pacific Railroad and
Chief Engineer of the Atlantic Division of the same line.

Shortly after he accepted this appointment the Colorado River broke
through its banks and overflowed the valley known as the Salton Sea,
across which the tracks of the Southern Pacific Road were laid. The
Company was compelled to make a detour of approximately 100 miles
around the inundated region, but, under the direction of Mr. Brown,
they succeeded in closing the break with two massive dams, confining
the river to its ordinary channel and preventing the increase of the
Salton Sea.

While in California Mr. Brown invented an oil and sand separator, which
the Southern Pacific Company is now using throughout its oil fields. He
also invented a continuous water purifier and a special oil power-pump.
All these machines are now on the market.

Mr. Brown was a man of sterling integrity; one who regarded his
profession in the light of an obligatory public service. To this sense
of duty he sacrificed much, primarily the necessary relaxation and rest
from arduous labor, which undoubtedly accelerated the end of his useful
and honorable career.

In recognition of the valuable services he rendered in connection
with the levee protection work in New Orleans, Mr. Brown was made the
recipient of public honors and testimonials of appreciation.

He is survived by a daughter and two sons; the latter are preparing
to follow the engineering profession. His wife, who was Miss Joan Von
Vesterfeldt of New York City, died in 1903.

Mr. Brown was elected a Member of the American Society of Civil
Engineers on June 7th, 1899. He was also a Member of the Louisiana
Engineering Society.

=JOHN HENDERSON SAMPLE, M. Am. Soc. C.E.=[3]

DIED MARCH 4TH, 1910.


John Henderson Sample, the only son of Judge William Sample, was born
on April 3d, 1849, at Coshocton, Ohio. He entered Dennison University,
Granville, Ohio, from which he was graduated in 1872. After leaving
college, he was engaged on the early surveys of the Toledo and Ohio
Central lines, working up from Axeman to Division Engineer.

Afterward Mr. Sample served as Chief Engineer of the Cincinnati,
Lebanon, and Northern Railway, and Chief Engineer of the Cincinnati
and Georgia (now the Southern Railway), from Rome to Macon, Ga.,
except from Austell to Atlanta. In 1883, he made surveys for the East
Tennessee, Virginia and Georgia Railway (now the Southern Railway)
in Alabama. He then became Chief Engineer of the Alabama Improvement
Company, engaged in the location and construction of the Northern
Alabama Railroad, and the development of coal and ore lands and the
Town of Sheffield, Ala.

He was appointed Chief Engineer of the Toledo and Ann Arbor, on
location and construction from Hammond Junction to Durand; Chief
Engineer of location and construction of the Missouri Pacific lines in
Kansas, Colorado, and Missouri; and from 1887 to 1889, he served as
Chief Engineer on the construction of the Louisville, Henderson, and
St. Louis Railway, from West Point to Henderson, Ky.

Mr. Sample made examinations and reports on timber and mineral lands
in Kentucky, Tennessee, Virginia, and West Virginia, and in 1889, he
examined and reported on the Mexican National Railroad, from Laredo,
Tex., to the City of Mexico.

From 1889 to 1896, he was Chief Engineer of location and construction
and General Superintendent of operation of the Pittsburg, Akron,
and Western Railroad, from Delphos to Akron, Ohio. In 1897 he was
appointed General Superintendent of the Cleveland, Akron, and Columbus
Railroad, which position he held until this road was purchased by the
Pennsylvania Company, in September, 1899. From that date to the time of
his death, Mr. Sample was in the employ of the Pennsylvania Company,
as Assistant Engineer, being engaged on line and grade revision and
special work.

His father being a lawyer and Judge, he partook of his judicial nature,
and all his lifework was based on the broad foundation of equity and
honesty of purpose. He was a man of unobtrusive manner, retiring
disposition, and unpretentious ways.

On June 7th, 1876, Mr. Sample was married to Miss Virginia Hughes. His
wife died on June 24th, 1889.

Mr. Sample died suddenly in the Fort Pitt Hotel, at Pittsburg, Pa., on
March 4th, 1910. He intended to leave for New York City during the day
to bid farewell to his son, who was Assistant Engineer on the Madeira
and Mamoré Railway, in Brazil, and had been spending his vacation of
three months with his father.

To his children, and to those who knew him intimately, Mr. Sample
leaves a memory of a life well rounded out by noble endeavor, and a
fixedness of purpose to know and do the right. He was conscientious in
every act and thought, a man of deep religious conviction, and though
called suddenly from his earthly labors, he was ready for the higher
service and duty.

Mr. Sample was elected a Member of the American Society of Civil
Engineers on October 6th, 1886.

=JACOBUS VAN DER HOEK, M. Am. Soc. C.E.=[5]

DIED DECEMBER 22D, 1909.


Jacobus Van der Hoek, son of the late Gysbertus Van der Hoek and
Johanna (Tupers) Van der Hoek, was born at Goes, The Netherlands,
on March 19th, 1862. He received his early education at the Public
Schools, and was graduated from the High School of his native town in
August, 1879. In September of the same year he entered the Polytechnic
School at Delft, The Netherlands, from which he was graduated, as Civil
Engineer, in July, 1883.

During 1884 Mr. Van der Hoek was employed as Inspector on the
construction of a dike across the "het slaak," a shallow tidewater
1-1/2 miles wide, and made surveys and soundings for a record map of
adjacent waters covering an area of 6 sq. miles.

In 1885 and 1886 he was employed by the Dutch Government as Assistant
Engineer in charge of a party, to re-survey the principal rivers of
Holland, and triangulated about 25 miles of river.

During 1887 Mr. Van der Hoek was Engineer in charge of the submarine
shore protection for the "Polder of Schouwen," The Netherlands. In 1887
he left his native land for the United States, arriving in New York
City, on December 25th.

From the latter part of 1888 to the beginning of 1890, he was employed
by the Wheeling Bridge and Terminal Railway Company, at Wheeling, W.
Va., under the late Job Abbott, M. Am. Soc. C.E., Chief Engineer.
The work comprised steam railway construction, a bridge 2,000 ft. in
length, including one span over the Ohio River, 525 ft. long, and three
tunnels from 400 to 2,400 ft. long, all double-track and heavy work
throughout. The Engineer who was in charge of the work, writes:

    "Mr. Van der Hoek reported to me as Chief Draftsman and
    Office Assistant during the period above mentioned. He was so
    capable and earnest in all of his work, and so well qualified
    to perform it, that our relations were not only uniformly
    pleasant, but they marked the beginning of a friendship that
    lasted until the deplorable end of Mr. Van der Hoek's useful
    life."

In 1890, Mr. Van der Hoek entered the service of the Lehigh Valley
Railroad and continued with this Company until July, 1909; during
this time he was successively engaged as Chief Draftsman, Assistant,
Resident, and Division Engineer. During the extension of the main line
of the Lehigh Valley Railroad, from Sayre to Buffalo, he was employed
as Chief Draftsman, designing masonry and other structures, also as
Assistant and Resident Engineer in charge of certain sections of the
line. Paul S. King, M. Am. Soc. C.E., the Chief Engineer in charge
of the construction of this 175 miles of double-track railroad, soon
recognized the exceptional engineering ability of Mr. Van der Hoek, and
appointed him, successively, Assistant and Resident Engineer in charge
of several sections; of his success and ability, Mr. King writes:

    "The sad and sudden death of Mr. Van der Hoek was indeed
    a great shock to me and his many friends in the Lehigh
    Valley System, particularly in New York State, his field of
    professional work for so many years.

    "I highly regarded his technical ability, sterling character,
    and untiring industry, both in the field and office. During the
    time he was engaged with me (nearly four years), he filled the
    positions of Chief Draftsman, Assistant, and Resident Engineer,
    and earned the respective promotions by the zeal and energy
    which was always characteristic of him with any work he had
    in hand. He continued throughout the period of construction,
    a record not equalled by any of the dozen or more Resident
    Engineers connected with that work. It was this observation of
    his conduct and activity in executing his work that warranted
    me to have confidence in his ability to take up the work to be
    done after the Operating Department took charge of the line,
    recommending him as the Engineer for Maintenance of Way of part
    of the new line."

In 1893, Mr. Van der Hoek was appointed Division Engineer of the
Buffalo Division of the Lehigh Valley Railroad, and had charge, under
the Superintendent of Maintenance of Way, of constructing stations,
water stations, coal trestles, wharves, stone ballasting the line,
building storage yards, rebuilding bridges, etc.; he continued in this
position until July 1st, 1909.

One of his associates on the Lehigh Valley Railroad writes:

    "I was intimately acquainted with Mr. Van der Hoek and his
    work from 1894 to the time of his death, and as a co-worker
    on the Lehigh Valley Railroad it is a privilege to testify to
    his exceptional engineering ability, his strong, unflinching
    character, his untiring energy, and implicit adherence to the
    lines of duty. He had exceptional executive ability combined
    with a thorough knowledge of details. It was these qualities
    that made him so successful in his work.

    "Mr. Van der Hoek was a sober, unassuming, and honest man, a
    generous and respected superior to his subordinates, a true
    friend, ever ready to assist an aspiring young man to greater
    knowledge and better positions; by these he will be truly
    missed and mourned."

On July 12th, 1909, Mr. Van der Hoek entered the service of the Lehigh
Coal and Navigation Company, as Civil Engineer, under the General
Superintendent of that company, at Lansford, Pa., to take charge of
the railroad maintenance, water supply, land surveys, and new outside
construction, on the extensive mining properties of that company in the
anthracite coal fields.

Mr. Van der Hoek's exceptional ability was thoroughly recognized by
his new employers, and his work and its results were fully appreciated;
he had but laid his plans and perfected a proper organization when,
on the afternoon of December 22d, 1909, while inspecting the work of
laying a new water main through the Lansford, Pa., tunnel, he met his
death by being run over by an engine, and his successful professional
career was thus sadly ended. His Assistant, who had accompanied him on
this inspection, met with the same lamentable fate.

On May 30th, 1896, Mr. Van der Hoek was married, in New York City, to
Johanna Van der Bent, and is survived by his wife and two children.

He was elected a Member of the American Society of Civil Engineers on
April 7th, 1897.

=LUTHER ELMAN JOHNSON, Jun, Am. Soc. C.E.=[6]

DIED MARCH 23D, 1910.


By the death of Luther Elman Johnson, the Engineering Profession has
lost a bright and able young engineer whose career, though short, gave
promise of a steady rise and a brilliant future.

Mr. Johnson, the son of Mr. and Mrs. M.D. Johnson, of Lawton, Okla.,
was born in Union, West Va., on August 10th, 1881. Most of his
childhood and early manhood, however, were spent in Missouri. He
received his High School training at Nevada, Mo., and his technical
education at the Missouri State University, from which he was graduated
in 1904, on his completion of the four years' course in Civil
Engineering. In connection with the training at the University, Mr.
Johnson, on graduation, was appointed and commissioned Brevet Second
Lieutenant, in the National Guard of Missouri, by the Governor of the
State.

His professional work began shortly after graduation, with his
employment in the United States Reclamation Service, in connection with
investigations of reservoir sites for the storage of irrigation water
in Oklahoma. Following this, Mr. Johnson was transferred to the Garden
City, Kans., pumping project, where, from 1905 to 1907, he was engaged
in concrete construction and other work. In the latter part of 1907,
he was transferred to the Minidoka, Idaho, pumping project, where, as
Assistant Engineer, he was engaged until shortly before his death.

His work on the latter project was in connection with the location and
construction of canals, and he was in active charge of the building
of a large number of small reinforced concrete and timber structures
and bridges for the irrigation system. In prosecuting this work, Mr.
Johnson showed ability of the first order, and gave evidence, by his
conscientious, thorough, and careful work, of great promise for the
future.

In March, 1910, his health failing, he returned to his home in Lawton,
Okla., to recuperate from a general breakdown, but pneumonia set in,
and he died on March 23d.

Mr. Johnson was a young man of sterling qualities and rugged honesty;
his life was clean and strong, his character sweet and lovable, and his
capabilities exceptional. Untiring devotion to and interest in his work
were traits which had won for him the deepest respect of his associates
and those who worked under his direction, and his death was a keen
loss, not only to his family to whom he was a devoted son and brother,
but to his many friends and to all those with whom his work brought him
in contact.

Mr. Johnson was elected a Junior of the American Society of Civil
Engineers on September 6th, 1904.
