About Ernst Marcus (zoologist)
Ernst Gustav Gotthelf Marcus (8 June 1893 – 30 June 1968) was a German zoologist, occupant of the chair of zoology at the University of São Paulo from 1936 to 1963, and co-founder of the Oceanographic Institute of the University of São Paulo. == Life == Marcus was born in Berlin in a Jewish family, the son of Georg Marcus, a jurist, and Regina Schwartz. As a child, he lived near the Berlin Zoo, where he observed all kinds of animals, and collected beetles. He studied at the Kaiser Friedrich Gymnasium and later entered the Friedrich Wilhelm University to study zoology. He began his doctoral studies in the Entomology Department at the Berlin Museum and, in 1914, he published his first zoological work. However, his studies were later delayed due to World War I, where he fought as a soldier, and his second work, a thesis on Coleoptera, was published only in 1919, when he received his doctorate. After graduation, he continued to work at the museum and was assigned to the Bryozoa collection. Without a resident specialist to teach him, he learned everything about the group on his own. In 1923, Marcus obtained the 'Privat-Dozent', a credential that permitted him to teach at the university level. Thus, he became a professor at the Friedrich Wilhelm University.
