Brown was hired as a general laborer by the Smithsonian in 1852 under Henry. Initially, he built exhibit cases, cleaned and moved furniture for the Institution, and shortly thereafter became the supervisor of a small group of Smithsonian workers. Brown developed a close relationship with then Assistant Secretary (and later the Smithsonian’s second Secretary) Spencer F. Baird, a naturalist, and the two worked together closely until Baird’s death in 1887. Baird trusted Brown implicitly and when out of town relied on Brown to be his “eyes and ears” of the Institution. Brown and Baird frequently corresponded about the operations of the Smithsonian, city events, and their personal lives, sharing a wry sense of humor about life. From their letters we learn that Brown entertained visitors, handled the mail, made travel arrangements, and paid the household staff for the Baird family. We also get a sense of a free African American man’s perspective on the progress of the Civil War, as it raged around him.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
