Proteus presents acclaimed trans writer Tabby Lamb’s (A Grievance of Witches, Happy Meal) new play about the true story of Michael Dillon and Roberta Cowell, who met in 1949 and were the first people in the UK to undergo gender affirmation surgery, carried out in Basingstoke. Inextricably entwined before parting after just three years, never to speak to each other again, the show charts their journey and brings them together for one last impossible encounter across time and space. Performed by majority a trans and non-binary cast who switch between roles, The Law of Mayhem uses magical realism and aerial circus as a physical vocabulary to tell the story of two lives that made their mark in history and forged a path for generations to come.
During her long life, Roberta had been a Spitfire pilot and was one of ‘The Few’, she also had a life-long passion for motor-racing and raced competitively before and after her medical transition. Michael had been President of the Oxford University Women’s rowing team and was a research scientist before joining the Merchant Navy as a doctor. He was a prolific published writer and later moved to India to devote his life to Buddhism. After reading Michael’s book Self: A Study in Ethics and Endocrinology, Roberta sought him out, and was introduced to his surgeon, Sir Harold Gillies. Whilst the doctor was unable to operate on Roberta because the Law of Mayhem stated that he could not castrate a healthy man, the three found a loophole – Michael started the surgery, and Dr Gillies completed it.
Writer Tabby Lamb said, “Michael and Roberta are icons who have come to represent a lot to the trans community. This play endeavors to get beyond the headlines and the 'firsts' and interrogate what they truly meant to each other, and how neither could have changed the course of history alone. At a time when trans rights are so up for debate, it's been so interesting diving into a point in our history when we were anonymous and our medicalisation had only just begun. On a personal note, exploring their journeys leading up to, during and after their bottom surgery, whilst I wait on endless NHS waiting lists for my own, has indeed been eye opening.”

To accompany the show, Proteus is collaborating with Historians, Academics and researchers to create a free digital resource that will bring into focus these extraordinary lives, and their place in British Trans history.
