Matthias Trentsensky served in the Austrian army, and took part in the campaigns of 1814-1815 against the French. In 1815 he retired with the rank of lieutenant (infantry). He studied engraving art and worked in the lithographic workshop of Adolph Friedrich Kunike in Vienna, and in 1819, together with his younger brother Joseph Trentsensky (1794-1839), opened his own lithographic publishing and office supply company (Papierwarenhandlung).
