He was an active member of the Collectors Club of New York which was developed by Lichtenstein and his friend Theodore Steinway.
An international philatelic judge during three decades, he was the commissioner of international philatelic exhibitions of 1913, 1926 and 1936 (the last two in New York). When he died, he was preparing the Centenary International Stamp Exhibition (CIPEX) of 1947.
In March 1945 in New York City, Theodore Steinway, others philatelists and Lichtenstein founded the Philatelic Foundation. It is a non-profit educational institution whose goals are philatelic expertise, research and publications. After 1947, his daughter Louise Boyd Dale continued to support the foundation.
His stamp collections and those of his daughter were sold during auctions at Harmer's between 1968 and 1971, between 1989 and 1992, and in 1997.
In 1948, the American Philatelic Society added him to its Hall of Fame list of the most important deceased philatelists.
In 1952, the Collectors Club of New York created a philatelic award called the Alfred F. Lichtenstein Memorial Award. Theodore Steinway was the first person to receive this prize for his work in developing philately. In 1996, this club named Lichtenstein "the Outstanding American Philatelist" of the first half of the 20th Century.
