Lionel Fry obituary

My former colleague Lionel Fry, who has died aged 87, was one of the most significant dermatologists of his generation. In addition to running a demanding NHS department at St Mary's hospital in London, he founded and led a pioneering research unit there which came up with new ways of alleviating psoriasis.

Lionel's work altered our understanding of the development and treatment of psoriasis, and pioneered the use of the immunosuppressant medication cyclosporin in managing severe cases.
