Henry Beckman is still making TV or movies occasionally according to the great website - http://us.imdb.com/searchhttp://us.imdb.com/search - this site says his first role (not credited on screen) was in 1953's "Niagara" which starred Marilyn Monroe and Joseph Cotten. He was also in 1964's "Marnie" with Tippi Hedren.
It shows him b. 26 November 1925 (think it was in Amherst or Yarmouth, NS but not sure).
He was related in some way (step-son maybe ?) to the BAILEY and THURSTON families of Amherst and Yarmouth NS. There used to be a hardware/appliance store "W.B. Bailey & Sons Limited" in Yarmouth until the 1980's. Some of the two families still live in the two towns which are about 5-6 hours drive apart.
Henry spent some of his high school years (early 1950's) at Yarmouth High School. Some older people remember his time there.
He was in Halifax (visiting/working ?) and may also have acted at Neptune Theatre in Halifax, NS in the 1970's (not sure) so he might also be registered with ACTRA (Assoc of Cndn Television & Radio Artists) or other professional theatrical agencies. ACTRA has branches in Halifax and Toronto. Try their website - http://www.actra.ca/http://www.actra.ca/ -
He might also be found through the Screen Actors Guild (SAG) of America through their website - http://www.sag.comhttp://www.sag.com -
Check out the NS phone listings under BAILEY and THURSTON. Yarmouth has tel #'s starting with 742-, 648-, 649- and Amherst has 661-, 667-. Henry would be related to some of these people.
