The school was founded in 1903 by Theresa Lawrence[1]: 203 and, Katherine Margaret Earle: two young women in their early thirties, both educated at the University of Cambridge. They acted as joint Heads of School during the years 1903–1930. It is a sister school of Roedean School in Brighton, England which was founded by three older sisters of Theresa Lawrence, namely Penelope, Millicent, and Dorothy.
The school began with 22 pupils, and was situated in a small house in Jeppestown, Johannesburg. In 1904, it relocated to its current site in Parktown, Johannesburg.[1]: 203
Sir Herbert Baker, a prominent architect responsible for many of Johannesburg's most historical houses and monuments, designed the original school buildings.[1]: 302 The oldest structures include St. Ursula's Building and Founder's Hall.
