Theodore K. Lorenz

His father was a textile specialist from Saxony who moved to the Russian Empire where Lorenz grew up.

He was educated at home and after studying three years at school he began to work from the age of 16 in a music company.

His father later moved to the Bogorodsk district where Lorenz enjoyed hunting excursions and began to work on taxidermy.

He explored the Caucasus and Kirghizistan as part of faunal surveys and was a specialist on the birdlife of the region.

Lorenz was an authority on Tetraonidae and Phasianidae and an illustrated monograph on the grouse was published posthumously in 1910.
