Second Saturdays – The Fresnel lenses of Kewaunee and Algoma Lighthouses
Join Wisconsin independent filmmaker Jake Heffernan for a rare look inside two of Lake Michigan’s historic lighthouses, as the Kewaunee and Algoma Lighthouses have their Fresnel lenses changed.
The pierhead lighthouses of Kewaunee and Algoma have marked the entrance to the small cities for more than 100 years. On June 6th, 2019, the 5th Order Fresnel Lenses from each lighthouse were carefully removed from the towers and replaced by LED lights. The Kewaunee lens is on display at the Kewaunee Historical Center. The Algoma lens was transported to Milwaukee where it’s awaiting display at the North Point Lighthouse Museum.
Jake Heffernan takes us through early light technology of US Lighthouses and the introduction of the highly efficient Fresnel Lens. Then, watch the tedious, nail biting process of the removal of the extremely delicate lenses from their towers.
