Alexander N. Vyssotsky
The list of accomplishments in observational astronomy attributed to
Alexander N. Vyssotsky is lengthy and impressive. In his 35 years of
astronomical work at the University of Virginia he published countless
works, with his best known probably being a catalog with five lists of
stars entitled Dwarf M Stars Found Spectrophotometrically. The work for
this book was done with a 10-inch prismatic camera to provide
spectroscopic parallaxes comparing giant M and dwarf M stars. He helped
to establish the time for one rotation of the Galaxy as 220 million
years. He worked on galactic kinematics and dynamics, concentrating on
the local Milky Way. He did extensive proper motion work and spent eight
years photographing the whole northern sky. Vyssotsky's story is much
more impressive than just this list of accomplishments.
Vyssotsky was born May 23, 1888 in Moscow, Russia. He received his
master's degree at the University of Moscow and taught at the Pulkova
Observatory until 1914. He served in the Czar's army in World War I and
became a lieutenant. He used his knowledge of French, English and
German as a wireless operator to intercept messages of other armies.
After the Russian Revolution, he fought with anticommunist White Army
forces in southern Russia under General Denikin. From there he moved to
Constantinople and then to Bizarte, Tunisia where he taught science to
Russian refugees.
A note in a German astronomical journal helped lead Vyssotsky to a
position at the University of Virginia in 1923. He arrived in September
to begin helping with the Boss star project. He also assisted Olivier in measuring double stars on
photographic plates. Over the next five to ten years, the proper motion
and double star photography monopolized Vyssotsky's time. It required
eight years for Vyssotsky and Peter van de
Kamp to complete the proper motion survey.
In 1929, he married fellow astronomer Emma T. R. Williams, who was
from Philadelphia and of a Quaker descent. She worked with her husband
as an astronomer at the McCormick Observatory until her
retirement. They had one son, Victor A. (Vic) Vyssotsky, who went on
to work as a mathematician and computer scientist at Bell Labs and later as the
Director of the Cambridge Research Laboratory of the Digital Equipment
Corporation. Vic is credited as one of the originators of Core Wars in
August 1961 (though it was called Darwin at the
time), which many years later unfortunately indirectly led to computer
viruses. Vic
was a member of the Triumvirate that
managed the creation of MULTICS, a precursor
to UNIX and LINUX. Vic coined the term process
for MULTICS.
In 1928, Vyssotsky was promoted from instructor to assistant
professor. He was promoted again, this time to associate professor, in
1937. In the mid-1930s, Vyssotsky began to record spectra of stars as
faint as 12th magnitude using the 10-inch Cooke camera and objective
prism, also referred to as the astrograph. The astrograph was a gift
from Mount Wilson Observatory, the
Carnegie Institution of Washington, and
the Carnegie Corporation. The project took twenty years to finish and
required Vyssotsky to be the primary user of the 10-inch
astrograph.
Vyssotsky also contributed astronomical work outside his spectral
survey. In October 1939, he unintentionally obtained the first spectrum
of a meteor, using the astrograph. His work on M-type stars began in the
early 1940's when he used the Cooke 10-inch and observed emission lines
in the spectrum of a dwarf M-type star, which provoked further
investigation. Starting in the early 1950's, Vyssotsky worked in
cooperation with the Harvard College
Observatory to abstract papers from Russian astronomical
journals. He also composed Russian abstracts for papers presented at
American and International conferences.
Throughout his tenure at UVa., Vyssotsky gave guests lectures around
the country and taught classes for undergraduate and graduate students.
He attended several meetings of the International Astronomical Union around
the world. He participated in American
Association for the Advancement of Science meetings. In the
mid-1950's he presented a paper at a conference on the Cosmic Distance
Scale. He also went to the 1957 conference on galactic system structure
in Stockholm, Sweden as one of only ten Americans in attendance.
Vyssotsky was also well respected for his participation in the
University of Virginia community. He played violin in fellow astronomer
Piet van de Kamp's Observatory Mountain
Orchestra and sat first chair. He collected the extensive collection of
Leander McCormick Observatory Papers from 1920 to 1945 and contributed
them to the Special
Collections of Alderman Library at UVa. In December 1953, he was
honored by election to the Raven Society, a
select society at the University of Virginia.
Vyssotsky retired on June 30, 1958 after 35 years on UVa.'s faculty. The
vacancy produced by his retirement was not filled immediately, putting
an end to Vyssotsky's lengthy proper motion and astrometry
programs. Vyssotsky died on December 31, 1973 in Winter Park, Florida at
the age of 85. He was survived by his wife, Emma, and their son
Victor.
