Jules Aarons (October 3, 1921 – November 21, 2008) was an American space physicist known for his study of radio-wave propagation, and a photographer known for his street photography in Boston.

Early on, he encouraged his BSS colleagues to set up numerous ionospheric monitoring stations, which later proved useful to the Air Force in designing its space-based communication and navigation systems.

[4] Later, while pursuing his college degrees and working as a scientist, he continued to develop his craft, taking his camera with him on business trips around the world.

Much of the West End was razed in the late 1950s as part of a large-scale urban renewal project, making Aarons's photographs of the area especially important for historical purposes; the Boston Public Library has an extensive collection of his work.

Unlike many of his contemporaries, Aarons chose not to focus on the lives of the downtrodden, writing in his notes: "I resolved to capture the day-to-day life experiences of the people, avoiding scenes of poverty."

His street scenes are often lively and vibrant, populated by ordinary people who are portrayed with dignity, evincing a fundamentally humane outlook.

He was keenly interested in the way people presented themselves in public: often with flair, as in Boy in Front of Girls, North End, 1955 (shown), in which a young man, presumably Italian-American, strikes a dramatic pose for the camera.
