Mr. Sackheim, Harry Scherman and Robert K. Haas in 1926 founded the Book-of-the-Month Club, the nation’s first direct-mail book club. Eleven years earlier, Mr. Sackheim had formed a New York advertising firm in partnership with Mr. Scherman

Two years after the book club was founded, Mr. Sackheim sold his interest, moved to Cleveland and went to work for the Brown Fence and Wire Company. Over the next 15 years he rose to the presidency of Brown Fence, which made fighter-plane wings in World War II.

Near the end of the war, he moved back to New York and in 1945 opened his own direct-mail advertising agency, Maxwell Sackheim & Company.

Mr. Sackheim, the author of ”My First 60 Years in Advertising” and ”How to Advertise Yourself,” was named to the Copywriters Hall of Fame in 1975.
