Ampad was founded in 1888 by Thomas W. Holley, a paper mill employee, in Holyoke, Massachusetts. At the time, Holyoke was a major papermaking center. Holley began purchasing the rejects, or "sortings", from local paper mills, cutting the paper, inscribing rules on it, and binding it into pads which he could sell at a discount. Within a year, Holley's business filled a whole floor of a commercial building on Holyoke's Main Street. By 1894, the business grew to occupy an entire building, at the corner of Winter and Appleton Streets in Holyoke, and in 1909, the size of its facilities there were nearly doubled. By the end of World War II, the company had expanded outside of Massachusetts and established international footholds.
