John B. Glass (1929-2015), born in Hawaii, majored in economics at Yale and earned a Ph.D. in archaeology at Harvard. He became an authority on Pre-Columbian hieroglyphics manuscripts, publishing numerous papers and books on the subject. In 2016 the John B. Glass collection of rare books and his papers were donated to Cal State LA Special Collections and Archives. The personal papers include publications and notes by John B. Glass related to his research on Mesoamerica. The rare books were separated from the papers and integrated into the Mesoamerica and Colonial Mexico Rare Book Collection. The entire collection also consists of two other book collections, which belonged to Scholar of the Aztecs, H.B. Nicholson and book collector Wayne Ruwet.
