Gerard Kuiper
Gerard Peter Kuiper , born Gerrit Pieter Kuiper (
Dec 7 1905,
Harenkarspel (
Tuitjenhorn) –
Dec 23 1973,
Mexico City) was a
Dutch American astronomer who became a
naturalized citizen of the United States and lived most of his life in his new homeland. Kuiper, the son of a tailor in a rural village in
North Holland, had an early interest in astronomy. He was blessed with an extraordinarily sharp eyesight, allowing him to see magnitude 7.5 stars with the naked eyes, about four times fainter than visible to normal eyes. He went to study at
Leiden University, where at the time a very strong number of astronomers had congegrated. He befriended fellow students
Bart Bok and
Pieter Oosterhoff and was taught by
Ejnar Hertzsprung,
Antonie Pannekoek,
Willem de Sitter,
Jan Woltjer,
Jan Oort and the physicist
Paul Ehrenfest. Kuiper finished his doctoral thesis on binary stars with Hertzsprung in 1933, after which he immediately traveled to
California to become a fellow under
Robert Grant Aitken at the
Lick Observatory. In 1935 he left to work at the
Harvard College Observatory where he met Sarah Parker Fuller, whom he married on June 20, 1936. Although he had planned to move to
Java to work at the
Bosscha Observatory, he took a position at the
Yerkes Observatory of the
University of Chicago and became an American citizen in
1937.
