Charles Findeisen (1919-2007) was an aerial photographer hobbyist turned professional and spent most of his life flying airplanes. Findeisen consulted for real estate development concerns, engineering firms, and construction companies among others. Virtually all of his work was in the tri-state region of New Jersey, Pennsylvania, and Delaware.

This collection contains his aerial photography from 1962 to 2000. It is comprised mostly of negatives but does include some photographs. Many of his subjects were photographed over time at regular intervals. This is particularly true of real estate development programs and building projects. But there is also one-off material of current events, local places, and landmarks.
