USSR 1956 – F. A. Bredikhin
Fyodor Aleksandrovich Bredikhin
(1831–1904) was a Russian astronomer best-known for his
work on the structure of comet tails; his surname is also
written as Bredichin, and his first name as Theodor. He was
director of Pulkovo Observatory, near St Petersburg, from 1890
to 1895. Fittingly, this stamp, issued on the 125th anniversary
of his birth, shows a comet hovering over the domes of Pulkovo
Observatory. Incidentally, the stamp really was printed on
brown paper – the colour is not due to ageing.
