Join Fairmount Park Conservancy’s John Sigmund, Director of Partnerships and Sponsorships, and local historian Thomas Keels, author of Sesqui! Greed, Graft, and the Forgotten World’s Fair of 1926, for a lecture and walk focused on the history of South Philadelphia’s beloved FDR Park.

In the early 20th century, the site of current-day FDR Park became League Island Park, part of a grandiose development scheme called the ‘South Philadelphia Improvements’. The Olmsted Brothers, sons of renowned Central Park designer Frederick Law Olmsted, were hired to transform the swamps of South Philadelphia into a natural wonder. Then, in 1926, the park was chosen to host the world’s fair, the Sesquicentennial International Exposition. While there are few physical remnants left from the Sesquicentennial, it brought the landscape closer to what we know today.

We’ll start off with a 45-minute presentation inside of the American Swedish Historical Museum, which itself has ties to the Sesquicentennial, before transitioning to a walk and talk through the north end (Pattison Avenue adjacent) of the park. On the walk, we’ll highlight points of park plans’ past and future, stopping at places such as the FDR Park Boathouse, the new Gateway Plaza, and the site of the Sesquicentennial’s ‘High Street’, a popular exposition built by the Women’s Committee near present-day Pattison Lagoon.
