C. Richard Johnson, Jr. was born in Macon, GA in 1950. He received a PhD in Electrical Engineering from Stanford University, along with the first PhD minor in Art History granted by Stanford, in 1977. After 4 years on the faculty at Virginia Tech, he joined the Cornell University faculty in 1981, where he is the Geoffrey S. M. Hedrick Senior Professor of Engineering and a Stephen H. Weiss Presidential Fellow.
At the start of 2007, following 30 years of research on adaptive feedback systems theory and blind equalization in communication receivers, Professor Johnson accepted a five-year appointment as an Adjunct Research Fellow of the Van Gogh Museum (Amsterdam, the Netherlands) to facilitate the interaction of art historians and conservation specialists with algorithm-building signal processors. In 2012, Professor Johnson was appointed a Scientific Researcher of the Rijksmuseum

Exhibition, research project highlight learning from Rembrandt’s art

More than 60 impressions by the Dutch artist across a wide variety of subject matter – self-portraits to landscapes – are included in “Lines of Inquiry: Learning From Rembrandt’s Etchings,” through Dec. 17. The exhibition and accompanying catalog highlight learning and teaching using academic collections and explore Rembrandt’s artistic process, such as his practice of reissuing small editions of prints after making subtle changes to the plates.
