April 15 | 6pm | Wavertree | Free
Kick off your Earth Day celebrations with filmmaker Jon Bowermaster for a special screening of his recent documentary The Keeper, which explores the life and legacy of John Lipscomb who spent 25 years patrolling the Hudson.
Cantankerous, charismatic, and deeply committed, Lipscomb reflects on his decades traveling over 80,000 miles by wooden boat to protect and defend what is known as “America’s First River.” Once a vital resource and, for a time, a dumping ground for a growing nation, the Hudson has faced decades of environmental challenges. At the forefront of its recovery has been Lipscomb, serving as both advocate and watchdog—taking on industrial and human pollution, weathering setbacks, and celebrating hard-won victories.
This film offers an in-depth look at the Hudson River’s environmental history and its global significance, highlighting the ongoing work of more than 300 “keepers” around the world. It’s a story of resilience, activism, and the enduring fight to protect our waterways.
The screening will take place in the intimate setting of the 1885 tall ship Wavertree’s ‘tweendeck, creating a truly immersive experience. A Q&A with the filmmaker will follow the screening and a reception with wine and seltzer will close the evening. Preregistration is encouraged for this event. Walkups will be accommodated as possible. Access to Wavertree involves climbing a few stairs, walking up an angled gangway, and descending a few stairs onto the deck. The lower decks are accessible via stairs, while the upper deck requires navigating steep ladder-like stairs.

About the 1885 Tall Ship Wavertree
Wavertree was built at Southampton, England, in 1885 and, after a 24-year sailing career and circumnavigating the globe at least three times, is now the last remaining iron-hulled three-masted full-rigged cargo ship. Today, Wavertree is visited by guests of all ages from around the globe and serves as the centerpiece of the “Street of Ships” at the Seaport Museum. She was listed on the National Register of Historic Places on June 13, 1978 and symbolizes the profound influence of sailing ships, their intrepid sailors, and the bustling waterfront in shaping New York City into a modern metropolis. As a historic vessel with a fascinating past, Wavertree embodies the rich maritime heritage that played a pivotal role in transforming South Street into the vibrant heart of “Where New York Begins.”
