Annie Montague Alexander (29 December 1867 - 10 September 1950) was an explorer, naturalist, paleontological collector, and philanthropist. She founded the University of California Museum of Paleontology (UCMP) and the Museum of Vertebrate Zoology (MVZ). From its establishment in 1908 until she died in 1950 she financed the museum's collections and supported a series of paleontological expeditions throughout the western United States. Alexander herself took part in many of these expeditions, accumulating a significant collection of fossils and exotic game animals that she would later donate to the museum. Alexander is remembered by the University of California, Berkeley as one of the "builders of Berkeley" and as the benefactress of the museum.
