Lev Matsievych (1877–1910) is a bright, but, unfortunately, still forgotten figure in Ukrainian history. He was one of the first pilots of the Russian Empire, designed submarines, worked on the aircraft carrier project. He was also a great patriot, one of the co-founders of the Revolutionary Ukrainian Party (RUP). Among his comrades and acquaintances - M. Vorony, M. Mikhnovsky, S. Petliura, O. Oles, M. Kotsyubynsky and dozens of others from the constellation of Ukrainian intellectuals of the early twentieth century.

Matsievich's letters to M. Kotsyubynsky and M. Hrushevsky and a selection of photographs , most of which are published for the first time.
