Life Steinmann was born on 8 March 1779 in Lanškroun, Bohemia. He worked as a pharmacist in Lanškroun and Prague, during which time, he conducted botanical investigations in the Giant Mountains and in Glatzer Land. Later on, he studied pharmacy in Berlin as a student of Sigismund Friedrich Hermbstädt, then in 1806–1608 furthered his education at the University of Vienna, where his instructors included botanist Joseph Franz von Jacquin and naturalist Carl Franz Anton Ritter von Schreibers.
