Walter D. Gernet (1878-1928) was a civil engineer who worked for the Public Works Department in Philadelphia for fifteen years. After losing his position in 1918, he spent his remaining ten years working various engineering jobs. This collection of Gernet's diaries chronicles his daily life and covers eight years from the end of World War I until 1925. The diaries offer a view of an average workingman's day-to-day activities in a large urban center. This collection of diaries would be of great interest to social historians, especially those focused on early twentieth-century life in the greater Philadelphia area. Its detail encompasses work, family life, and interactions between family members and friends in the wider community.
