CodeLab was invented by David Arnow and Gerald Weiss who have directed and helped with its development since the beginning and to this day. Arnow and Weiss are computer science professors at Brooklyn College which is part of the City University of New York. They have been teaching Computer Science since Jimmy Carter was president, when gigantic IBM mainframes roamed the earth… or at least sat slowly humming to themselves in vast air-conditioned spaces.
Lots of others have made contributions, some of them quite major. Most of these folks were Brooklyn College students or alumni.
