The Kellogg Environmental Center will be hosting the presentation “Valley Views of 1902” by Patricia Sweeney on Saturday, May 28, 2022, at 1:00 p.m. Registration is required. In 1902, Naugatuck River Valley Area residents and most likely Frances Osborne Kellogg, an amateur photographer, collected a series of photographs stored as fragile glass stereopticon slides. Due to advancements in digital technology these images can now be shared as a PowerPoint presentation. The slides celebrate everyday activities in the Lower Naugatuck Valley, with an emphasis on Derby. They highlight important buildings and people at work in fields, stopping at local businesses, bicycling in the park, and viewing the original Stevenson Dam (among other similar activities). Join museum docent Patricia Sweeney of the Osborne Homestead Museum in learning from this special archival collection of farm workers, young women, immigrants, and African Americans from 120 years ago. This is a free event. To register please call 203-734-2513.
