Max Luciano Birnstiel was a Swiss molecular biologist who held a number of positions in scientific leadership in Europe, including the chair of the Institute of Molecular Biology at the University of Zurich from 1972 to 1986, and that of founding director of the Research Institute of Molecular Pathology (IMP) in Vienna from 1986 to 1996. His research focused on gene regulation in eukaryotes. His research group was the first to purify single genes, the ribosomal RNA genes from Xenopus laevis in 1965. He is also recognized for one of the earliest discoveries of a gene enhancer element in 1980. Birnstiel died in 2014 of heart failure during cancer treatment.
