Maria Linden (18 July 1869 – 25 August 1936) was a German bacteriologist and zoologist. Linden had to struggle to gain a university place, a degree and a doctorate because of her gender. In name only, she became one of Germany's first professors. She patented a type of bandage and won a prize for her investigations of butterfly wings. She was driven from office as a result of the rise of the Nazi Party in Germany.
