Loyd Sandgren (1916-2001) was a Jacksonville-based commercial photographer who primarily worked from the 1940s through the 1990s. After his death in 2001, the Jacksonville Public Library acquired a collection of over 14,000 prints and thousands of negatives from his family. These are archived in cold storage as part of the Jacksonville Public Library's Florida Collection. Digitization of the prints was undertaken to make some of the collection available for viewing online. The effort began in 2004 and was completed in 2011.
