Do you ever wonder about the history of the computer or smartphone you’re using to read our tour announcements? Please join us on Wednesday, July 25 for a tour exploring the long history of computing from ancient adding machines to mid-century punch cards and mainframes and more.

The System Source Computer Museum in Hunt Valley features a remarkable collection of artifacts including the Altair 8800, on which a young Bill Gates learned to code; an accurate replica of an Enigma cypher machine used by the German navy in 1942; and even an original iPhone which turned eleven years old last month. You can check out the museum’s collection on their website but, even in our digital age, the screen is no substitute for exploring history in person.

You can also find us leading a walking tour around Federal Hill on Sunday, July 22 for our ongoing Monumental City tours. We hope you are staying cool this summer and can stay tuned as we line up our fall tours, talks, and events.
