A prominent theosophist from Philadelphia and close friend of Krishnamurti, Robert Logan was a great contributor to the Happy Valley School. He and his wife Sara shared an unwavering devotion to Annie Besant and eagerly supported her vision for Happy Valley, to create a community of people who would help to move mankind beyond the present age of violence and materialism. Together with Louis Zalk, he was a key financial underpinning for the school and, upon his death in 1956, he left a third of his estate to Happy Valley.
