Johannes Max Proskauer was born in Göttingen, Germany. He attended the University of London
, which awarded him a B.Sc.
in 1944, a Ph.D.
in 1947, and a D.Sc.
in 1964, all in the field of botany
.
In 1948, Proskauer moved to Berkeley, California
, where he became an instructor in botany at the University of California, Berkeley
. He was awarded a Guggenheim Fellowship
in 1954. He became a United States
citizen in 1957.
Professor Proskauer's thesis research was concerned with the biology
and morphology
of the British species of the hornwort
Anthoceros
. Much of his life's work focussed on this group, and in 1951, he recognized and defined the genus
Phaeoceros
for the first time. He continued to work at Berkeley
on the morphology and cytology
on the hornworts and also the liverwort
s.
He died in 1970, leaving a leagacy of careful and meticulous study.
