Folk music aficionados Bill and Andy Spence retained photographs, newspaper clippings, posters, schedules, flyers, and audio of the Fox Hollow Festival, of which they were involved in through their Capital District folk organization, Pick'n' and Sing'n' Gather'n' (PSG). The Beers family (Robert, Evelyne, and Martha) of Petersburgh, N.Y. held the Fox Hollow Festival on their family farm celebrating the traditions of folk music and arts every year from 1966 to 1980. The Festival consisted of multiple days packed with folk singing groups, workshops, art showings, activities, entertainment, dancing, games, speakers, crafts, and special guests with camping and other site accommodations upon request. This festival served as inspiration for the Old Songs Festival created in 1981 by Andy. The passing of Robert Beers in May 1972 signaled a shift for the Fox Hollow Festival, and Bill and Andy's last year of participation was 1973. PSG were involved as volunteers with the festival from 1966 to 1973, and Andy resigned from the Fox Hollow Board of Directors in September of that same year.
The research laboratory at General Electric was the launching pad for some of Vincent Schaefer's most pivotal scientific work. This series contains research notes, photographs, reports (published and unpublished, internal and external), and correspondence relating to all of his more famous experiments as well as a range of lesser-known work accomplished during his years at the G.E. Research Laboratory in Schenectady. The materials cover topics such as smoke/artificial fog generation, surface chemistry, studies of ice and snow particles, and early cloud seeding. The series is divided according to areas of specific interest to Schaefer as well as correspondence and publications.
