The year 2019 was a seminal moment for both The American Ceramic Society and the Glass & Optical Materials Division. For GOMD, it was the 100th anniversary of its founding by ACerS (originally called the Glass Division, renamed in the 1990s). For ACerS, it was the convening of the 25^th International Congress on Glass in Boston, Mass. It was the fourth time ACerS had been given the honor of hosting this conference by the International Commission on Glass, and the decision was based to a large degree on it being the GOMD centenary.
