Entrepreneur. He is recognized as a very successful mask maker and prop fabricator. He was celebrated as "The Godfather Of Halloween," the pioneer of the original creator of Over-The-Head Rubber masks. He was the founder and namesake of Don Post Studios. His own curiosity prompted a backstage visit to examine Ringling Bros. and Barnum & Baily Circus, and producing clown Paul Wenzel's "Popeye The Sailor Man" full head mask. As Don Post's inspiration, the masks were manufactured as Over-The-Head Rubber Masks for commercial sale. His first such borrowed personality mask was of Esky the "Esquire Magazine" mascot. Other masks were of the World War II dictators of Hitler, Stalin, and Mussolini and Edgar Bergen's Charlie McCarthy and Mortimer Snerd, which were all sold at Marshall Field's Department Store in Chicago, Illinois. Migrating to Hollywood, California in the 1940s, he was discovered by early merchandise mogul Norma Jean Trietch, who procured his services to create the rubber heads for commercially sold hand puppets of the famous wrestler Gorgeous George. Around 1948 Wright-Trietch put together a deal with Universal Studios for Don Post to manufacture Over-The-Head masks of Universal's famed Frankenstein Monster, thus becoming one of that studio's very first commercial product licensees. For the Hollywood film industry, he made alien pods for "Invasion Of The Body Snatchers" in 1956, Asian masks for stunt soldiers in "Pork Chop Hill" in 1959, giant clown feet worm by Doris Day in "Jumbo" in 1962, mutation appliances for "The Haunted Palace" in 1963, and a foam latex mask of Peter Lorre, worn by the actor's stunt double Harvey Perry in "Comedy Of Terrors" 1964. He was one of Hollywood's first prop makers to own a vacuum-forming machine. In 1963 Post formed Studio Plastics, Inc. with partners and studio special effects men Bob Bonning and Milt Rice to create everlasting plastic sides of meat for "Irma La Douce" in 1961, directed by Billy Wilder for MGM Studios, with Shirley MacLaine and Jack Lemon, and light-weight auto bodies for "The Great Race" in 1965, directed by Blake Edwards for Warner Bros., also with Lemmon, and Tony Curtis. A partnership with longtime friend Verne Langdon began in 1963 and saw Don Post Studios spiral to international fame with the development of an entire series of Universal Studios makeup department quality Hollywood Horrors Character masks (later to gain immortality as The Calendar Masks, for a monster calendar featuring the famed false faces), including Lon Chaney's "Phantom Of The Opera", Boris Karloff's and also Glenn Strange's "Frankenstein Monster", Bela Lugosi's "Count Dracula", and Lon Chaney Jr.'s "Wolf Man," created by celebrated Post Studios sculptress Pat Newman, and conceived and promoted by then-co-owner from 1963 to 1968, Verne Langdon. The "Famous Monsters of Filmland Magazine" was created and published by James Warren and Forrest J. Ackerman, serving to fire their fame and create further familiarity with the classic monster masks, which soon became in high demand with high prices at Disneyland, Disney World, and quality magic and masquerade shops around the United States. Post made personal appearances, along with Ackerman, Langdon, and horror film star Tor Johnson, who appeared in "Plan 9 From Outer Space" and other films, at live Hollywood Monster Shows staged by outdoor entertainment guru L. Strock Rupert and his Stunt Stars from Screenland, and produced by Sid Koss, at Uni-Mart stores around Southern California. A horror mask of Tor Johnson, created the same year by Don Post Studios, became the company's #1 best-selling mask. In the late 1960's Langdon sold his half of the company back to Don Post. The mask mogul was then joined by his son Donald Post Jr., who went on to acquire licensing from 20th Century Fox and ApJac Productions to make "Planet Of The Apes" professional quality masks, followed by "Star Wars" full head masks, all for commercial sale. Don Post Studios also created the mask of scare character and mass murderer Michael Myers, of cult Halloween film series notoriety the Trancas International films starred actress Jamie Lee Curtis.
