 Gleason published few contributions to coding theory , but they were influential ones , and included " many of the seminal ideas and early results " in algebraic coding theory . During the 1950s and 1960s , he attended monthly meetings on coding theory with Vera <unk> and others at the Air Force Cambridge Research Laboratory . <unk> , who had previously worked in abstract algebra but became one of the world 's leading experts in coding theory during this time , writes that " these monthly meetings were what I lived for . " She frequently posed her mathematical problems to Gleason and was often rewarded with a quick and insightful response .
