[1] Stematsky was born in 1908 in Odessa, Russian Empire (now Odesa, Ukraine).

He studied under Isaac Frenkel Frenel in the Histadrut Art Studio.

[3] He held his first solo exhibition at the Tel Aviv Museum of Art at the age of 31.

[4] In the constellation of Israel art, Stematsky and Yehezkiel Streichman stand out as a pair.

Although each developed his own distinct, individual style, there are many points of affinity between them: a common background as students of Bezalel in the 1920s, a response to the influences of the Jewish School of Paris in the 1930s, and of the "modern" (late cubist) art in the 1940s and fifties, when they were also leading teachers in Tel Aviv.
