Baltimore, Md. — Funeral services were held November 8 for Alexander John ''Zandy'' Leaderman who died of injuries resulting from a fall at his home. As owner and founder of Rockland Industries, Leaderman made Rockland into one of the world's largest drapery linings manufacturers.

''He was one of the pioneer-type people that did so much for the textile side of American home furnishings,'' said Stan Fradin, President of Roc-Lon, a separate division of Rockland Mills. ''Without people like him, there wouldn't be this kind of industry in America today. He had tremendous courage, drive and a vision.''

After serving in the army, he purchased the company in 1947, which had a different name. Leaderman carved a niche in the industry for Rockland. ''He identified in the early years products that other companies were ignoring, namely linings. You might buy a zillion other fabrics to use as curtains, bedspreads, mattress, comforters but every one has to be lined.

''In the early '60s, when we developed the Roc-Lon brand name, we did for drapery lining, what Chiquita did for the banana,'' Fradin said. ''We breathed life into it.''

Fradin, who worked closely with Leaderman for 33 years, said there were two sides to Leaderman. ''Zandy was a duplex person. In terms of a business setting, he was a no-nonsense, nuts-and-bolts kind of guy, but he had a heart that was bigger than his body so that anybody who knew him couldn't help but notice it,'' Fradin said. ''When my daughter was born in 1967, he came running over to the hospital before I got there.''

Leaderman was also an active philanthropist, whose contributions created scholarships and fellowships at Johns Hopkins Hospital and Brandeis University. He served for 10 years as a boardmember and briefly as President of the Levindale Hebrew Home for the Aged. In the last two years, he set up at the Hebrew University in Jerusalem an exhibit in honor of the eighteenth anniversary of the Camp David Accord.

Colleagues said Leader-man was passionate about his work. ''He loved the company, the industry and his work. The day he fell he had worked from 6:30 a.m. to 5:30 p.m.,'' Fradin said.

Condolence letters to Shirley, a Rockland Corporate Officer and his wife of 50 years, demonstrate the breadth of Leaderman's influence and popularity in the industry. ''I've gotten messages from all around the world saying that he was their mentor or teacher,'' she said. ''I had one letter from Australia in which the man said that [Leaderman] chastised him when he made mistakes as he would his own son and praised him when he did well.''

Sources said that Mark Berman, Leaderman's son in-law, is the main successor. His title will be Chairman of the Board. Berman has been with the company for 18 years.

Leaderman is survived by his wife and his son, Stephen, Rockland's Vice President and Treasurer.
