Berthold K.P. Horn  Berthold Klaus Paul Horn (born December 8, 1943) is an American scientist working in the field of artificial intelligence and computer vision. He is Professor of Electrical Engineering and Computer Science at Massachusetts Institute of Technology (MIT). He is also Principal Investigator at the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT. Horn is the author of two books and over 300 articles. His research is focused on Machine Vision, Computational Imaging, Suppressing Traffic Flow Instabilities and Indoor Navigation. He became a member of the National Academy of Engineering in 2002 and received the Azriel Rosenfeld Award by IEEE in 2009. Horn was born in Teplice, German-occupied Czechoslovakia (currently in Czech Republic). His family emigrated from Germany to South Africa after World War II and Horn was brought up there. He joined the University of Witwatersrand in 1961 for his Bachelor of Science in Electrical Engineering studies. After completing his Bachelor's degree in 1965, Horn taught Numerical Analysis at the University. During this time, he also worked as a consultant for the South African Navy to help them predict tides in the harbors. One of his Professors, Derek S. Henderson, who contributed significantly in bringing the first computer to the University of Witwatersrand was, at the time, working on bringing a more powerful computer to the university. In order to facilitate the process and arrange the required software and equipment, Henderson asked Horn to travel to the U.S. During the trip, he visited several universities, took the GSAT examination and decided to study at MIT for his Master's degree and later Ph.D. After completing his Ph.D. in 1970, Horn traveled back to South Africa and briefly taught at the University of Witwatersrand. Later he moved back to the United States and started teaching at MIT. In 1970, he began teaching at MIT and continued teaching there for the next 4 decades, becoming Associate Professor in 1976 and Professor in 1984. In 1983, he was appointed as the Associate Editor of Computer Vision and Image Understanding. He also serves on the Editorial Board of International Journal of Computer Vision. Horn was instrumental in the conversion to scalable, hinted outline format (Adobe Type 1) of Donald Knuth's Computer Modern fonts, The American Mathematical Society (AMS) fonts, LaTeX fonts, Michael Spivak's MathTime and MathTime Plus, as well as Charles Bigelow and Kris Holmes' Lucida Bright, Lucida Bright Expert and Lucida New Math fonts, all used in mathematical typesetting.
