Renbrook School in West Hartford, a private school for children age 3 through grade 9, began in 1935 when several area families decided to start a progressive school. Originally named the Tunxis School, it was first located in a rented house on Albany Avenue in West Hartford. Within months it moved to a larger house at the corner of Farmington and Outlook Avenues and was renamed Junior School. In 1937 the school erected its own building on Trout Brook Drive. By the mid-1950s the enrollment had increased and the school needed to expand again. The next move would be to the estate called Renbrook. This was the name given to the West Hartford mansion built (c. 1931) by famed aviation engineer Frederick Rentschler and his wife Faye Belden Rentschler. Frederick Brant Rentschler (1887-1956) co-founded Pratt & Whitney Aircraft in 1925. In 1929 he purchased 80 acres on Avon Mountain and soon constructed a Tudor Revival/French chateauesque mansion on the site. After Rentschler‘s death his estate announced it would lease the mansion to a worthy non-profit. The Junior School was chosen and in 1958 moved to its new home, also taking the new name of Renbrook School.
