The borough’s timeline began in 1899 as the Thornburg family farmland was being prepared for development. In the early years, families from Pittsburgh and nearby towns were attracted by the Chartiers Valley, new Craftsman houses, a school, trolley and train service, and a country club and golf course. Only a few houses were built through the Great Depression and WWII, but two organizations - Community Club and Village Players - were formed to support the neighborhood, and each still has purpose and impact today. During the post-WWII growth into the 1950s and 60s, Thornburg expanded with mid-century modern development and a significant increase in residents. The next several decades of contemporary development also included transitions for the school into the Community Center and the golf course into the Conservation Park. Recent activities have been focused on renovating community assets, celebrating borough history, and expanding neighborhood activities.
