Johann Tobias Bürg

Born in Vienna, Bürg worked as astronomical assistant to Franz Xaver von Zach at the Gotha Observatory.

He subsequently became assistant at the Vienna Observatory, where in 1817 he succeeded as director after the death of Franz de Paula Triesnecker.

In 1799 he published astronomical tables on the Orbit of the Moon based on about 3,000 observations, that were praised for their accuracy.

For these astronomical tables, Bürg was made a member of the French Academy of Sciences.

In 1834 the crater Bürg on the Moon was named by Johann Heinrich von Mädler in his honour.
