Olive Wetzel Dennis was born in November of 1885. As a child, she was always building and tinkering with things. When she was 10, her father gave her a set of tools and she built a scale model of a streetcar for her younger brother – complete with seats that turn over and steps that move up and down.
She earned a bachelor’s degree from Goucher College in Maryland and a master’s degree in mathematics from Columbia University and then taught high school math for ten years. But she never gave up the idea of becoming an engineer. So she went to back to school and became the second woman to graduate from Cornell University with a master’s degree in civil engineering.
Dennis went to work in the engineering department of the Baltimore and Ohio (B&O) Railroad. She started as a draftsman, building bridges in rural Ohio.
Happy Ada Lovelace Day! Today, in honor of Ada Lovelace, the world celebrates all of the accomplishments of women in science, art, design, technology, engineering, and math. Each year, Adafruit highlights a number of women who are pioneering their fields and inspiring women of all ages to make their voices heard. Today we will be sharing the stories of women that we think are modern day “Adas” alongside historical women that have made impacts in science and math.
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.
