He won the prize for his book "Tennessee Williams: Mad Pilgrimage of the Flesh." In a press statement, Lahr commented, "You don't write books for prizes, but it’s amazing how thrilling it is to win the acknowledgement because the whole enterprise is so solitary, and there are so many good writers – it's a huge honour."
Also on the shortlist this year were "Our Time of Day: My Life with Corin Redgrave" by Kika Markham, "What do I Know?: People, Politics and the Arts" by Richard Eyre, "Covering Shakespeare" by David Weston and "I Know Nothing: The Autobiography" by Andrew Sachs.
The prize, established in 2008, is awarded for the best biography, autobiography or diary in theatre or show business published in the preceding calendar year. Led by Playbill magazine's London critic Ruth Leon, the panel for this year's prize comprised Kate Bassett, journalist and theatre critic for The Times, stage and screen actress Gemma Jones, and actor and writer Michael Simkins, whose book "The Rules Of Acting" was shortlisted for 2014's Sheridan Morley Prize.
The winner receives a £2000 cash prize.
