Mr. Freitag, who was known as "Buddy," produced in conjunction with his wife Barbara. He attended Baruch College, CUNY and graduated in 1953. After serving two years in the US Army, he embarked on a 17-year career in advertising, eventually rising to the position of vice-president at Grey Advertising Agency. He then co-founded United Financial of America, Inc., a national commercial mortgage banking and brokerage firm. The Freitags did not begin their producing career until Mr. Freitag sold UFA. They then began investing in Off-Broadway and Broadway productions, including Anna in the Tropics, The Goat, Or Who is Sylvia?, Caroline, Or Change, Dirty Rotten Scoundrels, The Drowsy Chaperone, West Side Story, Legally Blonde, In the Heights and All My Sons.
In 2007 Mr. Freitag became a full-fledged producer with a revival of Pinter's The Homecoming. He then followed that venture with a flurry of activity, joining the producing teams on such Broadway shows as November, Passing Strange, The Miracle Worker, Catch Me If You Can, High and Blithe Spirit.
He is survived by his wife Barbara, their four children, Larry Freitag, Eve Freitag, Harry Falk, Liz Freitag Dranoff, and seven grandchildren.
