Elias Loomis was born on August 7, 1811, in Willington, Connecticut,
one of six children born to Hubbel and Jerusha (Burt) Loomis. Hubbel was
a Baptist minister who studied at Union College and also received an
honorary masterˆs degree from Yale College in 1812. He sent Loomis to
public school and gave his son additional training in Greek and
mathematics at home. Loomis matriculated at Yale in 1826 and graduated in
1830. He taught at Mount Hope Academy near Baltimore for one year and
then entered Andover Theological Seminary in 1831.
1811 - 1889
In 1833, Jeremiah Day, president of Yale and author of the first American
series of mathematics textbooks, hired Loomis to be one of the tutors who
provided elementary instruction at Yale through recitation sections.
Loomis taught Latin, mathematics, and natural philosophy until 1836. He
also began scientific research during this period. For fourteen months in
1834 and 1835, he made hourly observations of the declination of a
compass needle in order to measure the earth's magnetic field. He worked
with Alexander C. Twining of the United States Military Academy at West
Point in 1834 to determine the altitude of shooting stars. Loomis also
made astronomical observations with Denison Olmsted, the professor of
natural philosophy and astronomy at Yale. They were the first Americans
to identify Halley's Comet when it returned in 1835. Loomis was elected
to the Connecticut Academy of Arts and Sciences in recognition of his
Western Reserve College
In 1836, the trustees of Western Reserve College, in Hudson, Ohio,
chose Loomis to be the institution's mathematics and natural philosophy
professor. (People from Yale had invested heavily in Ohio land.) Although
they could only offer an annual salary of $600, one-third to one-half
that paid to professors on the East Coast, the trustees did appropriate
$4,000 for Loomis to use to purchase instruments and books in Europe.
Accordingly, Loomis traveled to Paris and London for several months,
where he attended lectures by such scientists as Franƒois Arago and
Jean-Baptiste Biot, visited observatories, and purchased equipment to
build an observatory at Western Reserve. Throughout his travels, Loomis
sent thirty-six "Letters from Europe" to the Ohio Observer
(October 1836-November 1837).
Loomis assumed his professorial duties in 1837. In addition to lecturing
on natural philosophy and astronomy to the juniors and seniors and
performing experiments in the classroom, he supervised construction of
the observatory on the southwest corner of campusonly the third college
observatory in the United States. Beginning in 1839, Loomis delivered ten
papers to the American Philosophical Society in Philadelphia describing
the observatory and the observations he made there. For example, he
recorded the orbits of five orbits. Loomis also took a magnetic survey of
Ohio, Indiana, Illinois, and Missouri in 1839 to assist Joseph Henry. He
worked as well in meteorology, devising an atmospheric chart in which
places with equal barometric pressure were connected. He hoped that
information gathered by observers in the American South and West could be
used to warn citizens in the North and East of approaching
Loomis married Julia Elmore Upson in 1840. The couple raised two sons.
When Western Reserve began to pay part of Loomis's salary in food and
then fell in arrears at even that, the family decided to move. Meanwhile,
Hubbel Loomis had moved to Alton, Illinois, after Jerusha died in 1829.
He became active in the anti-slavery movement, sympathies shared by his
son; Hubbel's report on the murder of an abolitionist in 1837 was read
aloud in Hudson and heard by local wool merchant John Brown.
New York University
Loomis left Ohio to become the professor of mathematics and natural
philosophy at New York University (then called the University of the City
of New York) in 1844. That December, he observed an eclipse and
participated in the short-lived National Institute, a scientific society
in Washington, DC. Loomis prepared the first synoptic weather map, a new
way of representing data that influenced theories of storms and weather
prediction, in 1846. 1846 was also the year in which Loomis wrote his
first textbook, Treatise on Algebra. Several of Loomis's texts
became wildly popular, such as the 1848 Elements of Plane and
Spherical Trigonometry, which went through 76 editions by 1881. Some
of Loomis's textbooks were translated into French, Italian, Chinese, and
Arabic. H. A. Newton checked the proofs for many of the books. Between
1846 and 1850, Loomis conducted experiments in electricity and
telegraphy. He gave an account of American meteorology in the
Smithsonian Annual Report for 1847.
Despite his opposition to slavery, Loomis considered moving to the
University of Virginia in 1848. However, he instead was hired by
Princeton University when Joseph Henry became Secretary of the
Smithsonian Institution even though Loomis had not applied for the job.
Unfortunately, the social atmosphere in New Jersey was hostile to
Connecticut natives, so Loomis and his wife decided that he should go
back to NYU in 1849. (Former West Point mathematics professor and
textbook author Charles Davies came out of retirement to serve at NYU
during the year that Loomis was absent.) Henry encouraged Loomis to write
Recent Progress of Astronomy as one of the first works in a
proposed series of popular publications from the Smithsonian, but
editorial differences between the friends resulted in Loomis retrieving
his manuscript and taking it to the large, pioneering New York firm that
published his textbooks, Harper & Brothers.
Julia Loomis died in 1854, leaving Loomis to isolate himself in his work.
He received an honorary LL.D. from NYU in the same year. Between 1859 and
1861, he published a series of papers on the aurora borealis in
American Journal of Science.
Loomis returned to Yale to succeed Olmsted in 1860. He continued to
write mathematics and philosophy textbooks until 1869, ultimately selling
600,000 copies of his works. His attentions in research, though, were
mainly focused on meteorology during this phase of his life. In the
Smithsonian Annual Report for 1865, Loomis posited that the
intensity of auroras followed a pattern similar to the periodicity of
sunspot activity and magnetic storms. Loomis also conducted statistical
studies of cyclones and supported the convection theory. Between 1874 and
1889, he published twenty-three ¶Contributions to Meteorology¾ in the
American Journal of Science.
Loomis was elected to the National Academy of Sciences in 1873. In 1870
and 1880, he prepared genealogies of the paternal and maternal sides,
respectively, of the family of his ancestor, Joseph Loomis. When
Loomis died in New Haven, Connecticut, on August 15, 1889, he left
$300,000 of his textbook royalties to Yale in the largest bequest the
institution had received up until that time.
