From the West End Theatre History site:
Hugh Beaumont, famously known as Binkie Beaumont, was one of the most powerful West End theatre managers of his, or any other, generation.Thought for the day - not many people these days are known as "Binkie".
As co-founder and managing director of play producers H.M. Tennent Ltd, he controlled much of the West End for forty years. He was famously very publicity shy, avoiding his picture being in the papers and leaving scant details about his parents, upbringing, education or even his real name.
He worked out of a small office above the Gielgud Theatre (then the Globe Theatre) on Shaftesbury Avenue and at one time was running a staggering fourteen productions at the same time in London. From 1936 to 1973 the company produced over 400 plays, musicals and revues, covering every aspect of British theatre from big musicals such as My Fair Lady to the edgy new work of Joe Orton.
He touched the lives of many of the most famous writers and actors of the Twentieth Century, forming close working relationships with people such as Noel Coward, Terence Rattigan, Emlyn Williams, Cecil Beaton, John Gielgud, Vivien Leigh, Ralph Richardson, Peggy Ashcroft and Edith Evans.
Which is a shame.
Incidentally, the actress on the puppet-master's stage is Miss Angela Baddeley (later world-famous as "Mrs Bridges" in Upstairs Downstairs), whose 110th birthday it would have been today...
