wiesner and barton’s clinic

A British scientist fathered 600 children after founding a fertility clinic that promised to provide sperm donors from ‘intelligent stock’, it emerged yesterday.
The barrister found out in 1965, at the age of 12, that he was born from a sperm donor, but was never told who his biological father was. He finally discovered the truth through DNA tests and has subsequently made contact with 11 of his half-siblings, including documentary-maker Barry Stevens, who led research into the clinic. Mr Gollancz said he had mixed feelings about his unusual family history.
