Malcolm C. Dizer (1886-1978) was a British-American philatelist who is known for his first day covers and assembling a number of specialized postage stamp collections under the general topic of "History in Philately".
According to an autobiographical essay published in The Lamp (house organ of the Standard Oil Company of New Jersey, later known as Esso Oil, and now known as Exxon-Mobil; September 1951, Dizer began his work life as "European sales representative for a large American firm". He retired from that position, but in 1943, desiring to contribute to the war effort, joined the US Merchant Marine, serving as purser on troop ships crossing the Atlantic. He also served with as an aide to Bernard Baruch on the War Industries Board. Later, he worked for Esso as a licensed purser-pharmacist's mate on oil tankers. He retired from Esso in 1951 at the age of 65 — on which occasion he published his autobiographical essay. He lived in the Tudor City development in New York City, at 320 E. 42nd St. (Apt. 2604). Before the war, Dizer had begun to send handmade Christmas cards to his friends. For 1936, he included a set of stamps depicting King Edward VIII and his abdication message. That was the beginning of the "History in Philately" series [1].
In the 1951 essay, Dizer notes that he had already prepared seven such "booklets", or souvenir albums, including one for the 1950 National Literacy Campaign Issue.
