James Watson, Nobel's award-winning DNA scientist, who lost his job in 2007 to express racist views, abolished several honorary titles on Friday of the New York City, which he once led.
Cold Spring Harbor Laboratory said it was responding to Watson's comments in a television documentary broadcast earlier this month.
In the film, Watson said that his views on intelligence and race have not changed since 2007 when he told a newspaper he was "intrinsically gloomy about the prospect of Africa" because "all our social policy is based on the fact that their intelligence is the same like ours ̵
In the 2007 interview, Watson said that while he hopes everyone is alike, "people who have to deal with black co-workers say this is not true".
In this month's documentary, he said that genes generate a difference on average between blacks and whites on IQ tests.  The laboratory, called the latest comments "reprehensible" and "without science support," said that they effectively reverse Watson's 2007 written apology and recall. It said it had revoked three honors, including Chancellor Emeritus and Honorary Administrator.
Watson had long been associated with the lab, became his director in 1968, its president in 1994 and its chancellor 10 years later. A school in the lab called him.
On Friday, Watson's son Rufus said that his 90-year-old father was in a nursing home after an October crash and that his awareness of his surroundings is "very small."
"My father's statements can get him to become a bigot and discriminatory, "he said, but that's not true. "They only represent his rather narrow interpretation of genetic fate."
"My dad had made his lab life, but now the lab sees him a duty," he said.
James Watson shared a 1962 Nobel Prize with colleague Francis Crick and researcher Maurice Wilkins to discover in 1953 that DNA was a double helical as a long, slightly twisted ladder. The breakthrough was important in determining how the genetic material works.
The dual spiral became a widely recognized symbol of science, and Watson became well known far beyond scientific circles.
