Maria Wilman (1867- 1957) was a South African geologist and botanist. She was the first director of the McGregor Museum in Kimberley, South Africa and the second female South African to attend the University of Cambridge in England. In 1906 she undertook an important journey up to Kimberley, the Vryburg region and further north, collecting specimens, and amassing data on rock engravings which was the start of a project culminating nearly three decades later in her publication Rock engravings of Griqualand West and Bechuanaland. It remained the standard text on rock art in South Africa for nearly five decades. (wikipedia.com)
