Franz Heinrich Kaiser (25 April 1891 – 13 March 1962) was a German astronomer. He worked at the Heidelberg-Königstuhl Observatory from 1911 to 1914 while working on his Ph.D. there, which he obtained in 1915. During this time, Heidelberg was a center of asteroid discoveries and he discovered 21 asteroids during his time there.
The asteroid 3183 Franzkaiser was named in his honor

No image found of him, only lots of images of Franz Joseph I or Francis Joseph I, which was Emperor of Austria, King of Hungary, and the ruler of the other states of the Habsburg monarchy. ( The closest he came to Astronomy is all the stars on his chest )
