Ladislaus Weinek

[1][2][3] He was educated in Vienna, and worked for a period at the photography laboratories in Schwerin.

In 1874 he joined a German expedition to the Kerguelen Islands to observe a transit of Venus across the face of the Sun.

In 1883 he became a professor in Prague and was the ninth director of the Klementinum observatory.

He set up observing stations in Prague and Dresden (to observe the Andromedids shower of that year, which turned out to be very intense), and caught a 7mm-long trail on a plate in Prague.

[4] In collaboration with Karl Friedrich Küstner (in Berlin), he made measurements of the altitude of the celestial pole.
