Karl Ludwig Littrow

Karl Ludwig Edler von Littrow (18 July 1811 – 16 November 1877) was an Austrian astronomer.

Born in Kazan, Russian Empire, he was the son of astronomer Joseph Johann Littrow.

Under his leadership, construction of a new observatory began in Währing in 1872; he died, however, prior to its completion.

He is the great-great-grandfather of Roman Catholic Cardinal Christoph Schönborn.

He made contributions to a new edition of Johann Samuel Traugott Gehler's Physikalisches wörterbunch.
