If you’ve ever visited Fells Point on the Baltimore waterfront, you may have noticed an older man with a telescope.

His name is Herman Heyn, the city’s street corner astronomer.

For decades he’s set up in the same spot, inviting passers-by to peer through his telescope.

At StoryCorps, Herman (left) sat down with his nephew, John (right), to remember how he became a self-proclaimed “star hustler.”

Originally aired August 28, 2015, on NPR’s Morning Edition.
