Immaculate Heart High School was founded in 1906 by the Sisters of the Immaculate Heart of Mary, a Catholic religious order of women who trace their origin to Olot, Spain, where they were founded by Father Masmitja de Puig in 1848. Conaty, the sisters later purchased a fifteen-acre plot of land for $10,000 in the Hollywood Hills at what is now Western and Franklin Avenues. The property at that time was outside the city limits, flanked by olive and orange trees and approached only by a wagon road. On April 24, 1905, the ground-breaking took place for a grayish-white, red roofed edifice of Moorish, mission architecture. This convent building included classrooms for high school and elementary school students, boarding facilities for the girls, and living quarters for the sisters. In June 1906, six young women became the first graduates of the school which then had a total enrollment of 75 students. The curriculum developed to include Greek, Latin, French, Spanish, English, history, mathematics, physiology, chemistry, physics, music, art, and drama. In 1908, Immaculate Heart became the first private school in Southern California to receive college accreditation. Immaculate Heart soon established its reputation as an excellent college preparatory school for young women. By far the majority of its more than 9,000 graduates continued their education at colleges and universities across the country. They have served with distinction as artists, musicians, educators, journalists, doctors, lawyers, engineers, scientists and stars of stage and screen, to name but a few of the many professions and careers they have entered. Immaculate Heart graduates were often pioneers in professions not accustomed to having women.
