Marie Olga Rosenthal-Hatschek (18691942) was an Austrian painter known for her portraits.
Hatschek was born on March 28, 1869 in Lviv, Austrian Empire (now Ukraine). She studied at the Academy of Fine Arts in Vienna and also in Munich, Germany with Carl von Marr.
She was the wife of the Austrian zoologist Berthold Hatschek (1854-1941) and the sister of the pianist Moriz Rosenthal.
The Hatschek home was looted and destroyed in 1938 by Nazis, and most of the family's possessions were destroyed, including many of Marie's paintings. The Hatschek daughters were able to escape to America in 1939, taking Marie's surviving work with them, but neither Marie nor Berthold Hatschek were able to leave Europe.
Hatschek-Rosenthal died in 1942 in the Banjica concentration camp in what is now Belgrade, Serbia.
