Rosemont's Philadelphia Origins

Rosemont’s early history is linked to Philadelphia. Many of the board members of the Rosemont Development Company had links to the Washington & Mount Vernon Railway, which ran trolleys through Rosemont and was owned by Philadelphia-based investors. Early media reports about Rosemont noted that Philadelphia-based contractors were building houses, some of them designed by David Knickerbacker Boyd of Philadelphia (pictured below). Likewise, Rosemont was generally said to have been modeled on the Philadelphia suburb of Wayne – home of Frederic H. Teat, the President of the RDC c. 1911-17.
