Anyone remember DORHAR philatelic enterprises from early 60'

Harry Weiss
(July 24, 1888 – July 23, 1966) Illinois

Weiss was one of most influential and widely-read philatelic columnists of his time. As editor of Weekly Philatelic Gossip in the 1930s, he began a newsy column, “Inside Straight,” about the hobby, new stamps, inside stories and suggested “hot tips.” He also wrote another column, “Canadian Round Table,” for the paper. He continued the weekly “Inside Straight” until Gossip ceased publication in 1961. Almost immediately, Weiss began another column, “Stamp Market Tips,” published in Stamps from late 1961 until his death.

During his editorship of Gossip, Weiss serially reprinted several important out-of-print books. Among them was John N. Luff's The Postage Stamps of the United States (1943 reprint).

In 1946, Weiss organized the Midwest Philatelic Laboratory, offering a wide range of services to collectors and estates: appraisals, expertization, mounting, and suggestions for successful disposition of collections. His laboratory contained technical equipment available for use at only a few philatelic facilities. In 1961, he was joined by Dorothy Fleischli, forming Dorhar Philatelic Enterprises.
