Biographical Sketch
Henry Augustus Rowland was born in Honesdale, Pennsylvania on
November 27, l848, the son of a Presbyterian clergyman. He
graduated from Rensselaer Polytechnic Institute (Troy, New York)
in 1870 as a civil engineer and was engaged during 1871 in the
surveying of a railroad in western New York state. For a time he
taught at Wooster University, but in 1872 he returned to
Rensselaer as instructor in physics, becoming Assistant Professor
in 1874. Rowland spent a year abroad studying with Helmholtz in
Berlin, and examining physical laboratories in Europe. In 1876
he accepted the Chair of Physics, with charge of the laboratory,
in the newly founded Johns Hopkins University. He held this post
until his death in 1901. He married Henrietta Harrison in 1890.
They had three children, Harriet, Henry and Davidge. Rowland's original work was extensive and his findings drew on
numerous researches made under his supervision at Johns Hopkins.
Among his many notable achievements were his discoveries in the
determination of the mechanical equivalent of heat, and his
determination of the standard Ohm. He gained a world-wide
reputation by his large diffraction gratings. These were
exhibited at the National Academy of Sciences in 1883 and
subsequently at various international exhibitions. He served as
an engineering consultant for the harnessing of the water power
of Niagara Falls to create electricity. The last years of his
life were devoted to refining and marketing his version of the
multiplex telegraph. Numerous degrees and honors were conferred upon Rowland for his
scientific work. He received the degree of Ph.D. from Johns
Hopkins in 1880 and that of the LLD from Yale in 1895 and from
Princeton in 1896. He became a Chevalier of the Legion of Honor
in 1881 for service on the jury of the electrical exhibition at
the Electrical Congress in Paris that year, and in 1896 he was
made an Officer of the Legion of Honor. Scope and Content Note The collection spans the years 1793 to 1970, but the bulk of the
material is that created by Rowland and dates from 1868 to 1901.
The papers consist of correspondence, diaries, research
notebooks, lab notes and calculations, patents and agreements,
lectures, writings, bills and receipts, reprints, and newspaper
clippings. The collection is particularly strong in documenting Rowland's
contributions to the history of technology. His student
notebooks, writings and lab notes reveal much about the
experimental processes of physics in the late nineteenth century. The notebook series (Series 4) covers both Rowland's days as a
student at RPI and his years as a professor at Hopkins. The RPI
notebooks (Boxes 20-22) are useful for the information they
provide about physics and engineering training in the late
nineteenth century. Of particular interest are Rowland's notes
on lectures he attended in mechanics and astronomy, and his
technical drawing notebooks. Three items in the writing series (Series 5) also illustrate
Rowland's earliest work. They are "The Work Done on Unequal
Masses by Equal Froces in Equal Times" (1868), "The Magnetic
Electric Machine. Hints on the Improvement. September 1868,"
and his senior thesis, "Steam Engine with Variable Cut-off"
(1870). Before beginning his appointment at Hopkins, Rowland, at Daniel
Coit Gilman's suggestion, took an extended trip to Europe. His
aim was to study both experimental and teaching methods in
university physics departments. He visited Kings College,
Cambridge; University College, London; University of Edinburgh;
University Glasgow; College of France; Leipzig and Gratz. Rowland
kept a notebook with his impressions (Box 22). This, along with
his letters to Gilman (Ms. 1, Series 1) document the state of
European science in the late nineteenth century. Rowland depended on his graduate students to help him in his
research. Two of the notebooks from the Hopkins period contain
lab data collected by graduate fellows. An 1882 notebook (Box
25) contains experimental data on diffraction gratings compiled
by Charles Herschel Koyl; "Experiments upon R”ntgen's X-Rays"
contains results obtained by other students. The Johns Hopkins University series (Series 2) documents the
codification of scientific research in the late nineteenth
century. Rowland's reports on the work of the Physical
Laboratory, lists of lab supplies and books purchased, and
proposed floor plans indicate his desire to properly train a new
generation of physicists. Additional information about Rowland's
work in the Univeristy may be found in his letters to Daniel Coit
Gilman (Ms. 1, Series 1).
Rowland was interested in two significant scientific developments
of the nineteenth century: the telegraph and hydroelectric
power. He parlayed his expertise with electrical circuits into a
business venture when he founded the Rowland Multiplex Printing
Telegraph Company in 1898. Much of its success was due to the
work of Joseph Penniman and Henry Wiegand. Former students of
Rowland, the two set up and displayed the telegraph to the
public. Letters from them to Rowland in the Rowland Multiplex
Printing Telegraph Company series describe their efforts. The
bulk of the correspondence covers public trials in Jersey City
(1898-1899) and at the Paris Exhibition of 1900. Wiegand's own
student and research notebooks are in Ms. 127. In 1892, the Cataract Construction Company of New York undertook
a study to determine the best type of dynamo to use in the
proposed hydroelectric power plant at Niagara Falls. They
retained Henry Rowland as a consultant. Rowland reviewed
proposals by competing companies: General Electric,
Westinghouse, Atelier Oerlikon and Cie. l'Industrie; and
evaluated the recommendations presented by another consulting
engineer, George Forbes. When the company refused to pay
Rowland's final bill, he sued. Correspondence, research notes,
proposals and court transcripts form the Cataract Construction
series. Although both the Cataract Construction Company and the Rowland
Multiplex Telegraphic Company series contain most of the
correspondence relevent to their contents, additional material
may be found in the general correspondence series. For example,
Louis de Goll's (president of the Printing Telegraph Company)
letters to Rowland and correspondence from William Marbury, who
represented Rowland in the Cataract case, are filed
alphabetically in the correspondence series. De Goll's letters
illustrate the legal issues and increasing bureaucratization of
the patent process. The letters in the correspondence series comment mostly on
scientific developments. John Brashear, the manufacturer in
charge of the production of plates for Rowland's diffraction
gratings, wrote extensively to Rowland. Colleagues and former
students updated him on the status of their work. The correspondence series also contains Rowland's letters to his
family. Begun when he was a student at Rensselaer Polytechnic
(1874), and continuing through his tenure at Hopkins, they
illustrate academic and family life in the late nineteenth
century. Rowland kept informed of other scientific research through
several collections of reprints. Among his papers were the first
of three reprint collections. This was Rowland's personal reprint
collection and is Series 8 of Rowland's papers. Rowland also
owned a separate reprint collection which had been gathered by
George G. Stokes of the Royal Society. These reprints were bound
topically as were Rowland's and were cataloged in the Eisenhower
general stacks. The largest number of the Stokes Collection
volumes have the call number QC 3 S87 vol. 1-52. There are other
volumes of Stokes reprints under other call numbers. The third
collection of reprints formed the Henry A. Rowland Memorial
Library. These too were bound topically and have various call
numbers beginning QC 3 in the Eisenhower general stacks. There
are 128 volumes on topics such as absorption, metallic
reflection, electrical discharges in gases, ionization, magneto-
optics, spectra of the elements, spectrum memoirs, physics of the
stars, and the papers of William Wallace Campbell, A. Crova,
Elster, Julius Geitel, Julius Fenyi, George Hale, W.N. Hartley,
Angelo Secchi, Samuel Pierpont Langley, Eugen Cornelius Joseph
von Lommel, Ch. Montigny, Henri Poincare, Charles Piazzi Smyth,
George G. Stokes, Peter Guthrie Tait, Emilio Villari, H.C. Vogel,
F.L.O. Wadsworth, Weidemann and Schmidt, R. Wolf, and R.W. Wood. Series Descriptions Series 1: Correspondence. 15 boxes, 1868-1901. Rowland's incoming letters, some with copies of his replies, have
been arranged alphabetically by writer. A complete list of
correspondents is in the container list. There is some
correspondence relating to honors and awards in the Personal
Series Box 16. Correspondence regarding the Multiplex
Telegraphic Company and the Cataract Construction Company are in
Series 5 and 6. There are also family letters in this series. Rowland wrote to
his mother and sisters while at school and during his tenure at
Hopkins. The letters span 1865-1901. Correspondence of
Rowland's wife, Henrietta Harrison Rowland, and his daughter,
Harriette Rowland, are included here. Most of the letters are
incoming, with a few drafts of outgoing letters by Mrs. Rowland.
There is a selection of Henry Rowland's letters written to Mrs.
Rowland from the World's Columbian Exposition in 1893.
Other of Mrs. Rowland's letters were received after Henry's
death, and focus on various legal problems she encountered over
royalties on Rowland's patents. There are also folders of
invitations filed with Henrietta's correspondence. Series 2: Johns Hopkins University, .5 box, 1876-1901. This series contains material related to Rowland's activities at
The Johns Hopkins University. The main focus is on the Physics
Laboratory--reports, floor plans and supply lists--and Rowland's
diffraction gratings. Related material about the manufacture of
the gratings may be found in the correspondence series filed with
the Daniel Coit Gilman, John Brashear, and Frederick Paschen
letters. The JHU material also contains lists of the books in
Rowland's library, and a paper by a student, Park Morrill. The
items are arranged alphabetically by topic. Series 3: Personal. 4.5 boxes, 1876-1970. This series contains material about Rowland. Included are papers
about his honors and awards, photographs, visiting cards, bills,
printed material and newspaper clippings, and a Ph.D. thesis
about Rowland completed in 1970. There are two items filed in the oversize map case: a map of
routes of the Thomas Wilson Sons and Company steamers (1887); and
a copy of the University's commemoration of Rowland.
Series 4: Notebooks and Lab Notes. 19 boxes, 1868-1900. This series contains Rowland's student notebooks, notebooks he
kept on experiments, and loose pages of notes, writings, and
calculations on a wide variety of topics. The notebooks are
arranged chronologically; the lab notes alphabetically. The
container list gives the topics.
Series 5: Writings. 5 boxes, c. 1876-1901. This series contains drafts of articles by Rowland as well as
copies of his published works, arranged alphabetically. The most
complete collection of his printed articles is contained in the
reprints series (Series 8; see description below). The reprints
in the writings series, although duplicated in the reprints
series, contain corrections and comments in Rowland's hand.
Also, most of the manuscripts were published, so drafts may be
compared with the finished product. Some of the interesting
unpublished manuscripts include Rowland's notes on Thomas
Edison's patents, his argument against duties on imported books,
and a tribute to the British physicist, James Clerk Maxwell. In addition to the reprints series, Rowland's most significant
published works were gathered together after his death, and
republished in a memorial volume entitled Physical Papers of
Henry A. Rowland. This volume is included in the writings
series. Series 6: Rowland Multiplex Printing Telegraph Company. 4 boxes,
1898-1905. This series contains records of the company, research notes on
the telegraph, and sample transmissions from the telegraph, as
well as correspondence from Henry Wiegand and Joseph Penniman
about the development of the telegraph. Most of the material is
arranged chronologically. The sample transmissions, however, are
for the most part undated, and so have been simply boxed
together. Series 7: Cataract Construction Company. 2 boxes, 1892-1901. This series contains material, arranged alphabetically, on the
Niagara Falls hydroelectric project, sponsored by the Cataract
Construction Company. The lawsuit with the company is
particularly well-documented, as is Rowland's work for them.
There is related material in the correspondence series: see
especially Brown and Boverie Company, E. F. N. Mascart, William
B. Rankine, Coleman Sellers, Francis Lynde Stetson, Theodore
Turrettine, and Edward A. Wickes. Series 8: Reprints. 56 volumes Rowland kept a large collection of reprints on topics of his
research. These were bound in 56 volumes and the reprints date
from 1793 to 1901. The topics of the volumes are Electricity (28
volumes), Heat (8 volumes), Liquids (3 volumes), Mechanics (2
volumes), Gases (3 volumes), Apparatus and Methods (2 volumes),
Physics of the Earth (6 volumes), Solids (l volume), Chemistry (1
volume), Acoustics (l volume), and Physiological Physics (l
volume). A list of the most common journals collected in each
series is in Appendix 1. Photocopies of the titles of the
reprints in each volume are in Box 44. Twenty additional volumes of this Reprint Series hav been alienated from the collection.
These volumes are labeled "Light" and are in the Eisenhower
Stacks (call # QC3.L72v.1-20). Series 9: Patents, 1 box, 1893-1905. Copies of Rowland's patents and some of the supporting
application materials are contained in this series. The material
is arranged chronologically. Additional information about
Rowland's forays into patenting his work may be found in the
Whitman and Wilkinson and Edward Wilkes correspondence in Series
1. (Often a copy of a patent was filed alphabetically by name of the
patent holder in the correspondence series>) Box 1: Correspondence Stenographer's notebook, October 23, 1899.
