Bischoff was one of the first Bay-area artists to move away from abstract expressionism and into more figurative art. His work and the work of others who joined him in moving away from abstraction is referred to as the Bay Area figurative movement. The work above, Maroon Blouse, is from the period seen as his most important. Note that even though this is figurative he isn't trying for realism. His painting was about emotion not depicting reality.
Kishi graduated with a degree in physics and mathematics from Tokyo University of Science. He was a math teacher for a while but then started exhibiting with Tekkei Kai, a Japanese abstract group associated with the Kyoto Museum of Art. He moved to the USA in 1960.
He created with the canvas horizontally and used large brushes and sticks to drip paint. The piece below is Opus No. 60-145.
