I read about Dr Helena Wright in today's newspaper. A pioneering presence in women's health issues in the early 20th century, she was also remarkably forward-thinking and compassionate. Not to mention discreet. By employing the services of a Man Called Derek she enabled some 500 married women to conceive in the years after the end of WW1. This was done with the knowledge of their husbands, many of them rendered unable to father children following their wartime experiences.
It's a wonderful and oddly heartwarming story. Apparently a well-kept secret! Derek's surname is not revealed.
