Edith Ackermann was a beloved member of the Media Lab faculty from the early days of the Lab through the mid-90s, and continued to play an active role as a researcher, mentor, advisor, and friend to innumerable people throughout our community. A developmental psychologist by training, Edith devoted her career to researching the intersection of learning, play, design, and technology. She also contributed a great deal to the Media Lab’s intellectual fabric; for example, just this past March she joined a conversation about cybernetics hosted by Lab director Joi Ito.
