Born in Lodz, Poland, in 1926. he lived in Israel until his death in 2008.
In his early years as a painter, he might have been considered the last representative of Jewish art, Yiddish art, the art of the state painting of bright, pure color. He said of his paintings from that period:
"It is difficult to know whether Yiddish art will have a future, because the heirs of that culture that was almost destroyed by Nazism are few, I drew these paintings from the world that remained within me".
Since then, Jacob has changed his style quite a bit. While the wonderful softness of the colors remained, themes developed that combined the figurative, the figurative, and the abstract.
His abstract paintings take the viewer to other realms, to places where there is innocence, peace, serenity and endless traditions of assimilation of splashes of color scattered on the canvas that perfectly fit into a balanced, perhaps mystical work.
Wasover was perhaps one of the few artists in Israel whose income was solely from painting.
His works are found in many important collections in Israel and around the world.
