Derrick became a patient at Charing Cross Hospital where he was prescribed hormones. She transitioned to Della in 1970 with surgery from Dr Georges Burou in Casablanca.
She was the founder of GRAIL (Gender Research Association International Liaison), which campaigned for transsexual rights. She put on the pioneering gender conferences at Leeds 1974, and Leicester 1975 (the latter was attended by the sociologist, Dave King, who would later write on transgender persons).
In 1974 she also co-produced a BBC2 Open Door program on transsexuals which featured the Member of Parliament for Pontypool, Leo Abse, who had introduced the private member’s bill to decriminalize homosexuality that had become law in 1967.
She also wrote a pamphlet on Theocratic Socialism, which she dedicated to Charlotte Bach.
