The $60 million Wellcome Collection in London is filled with items collected by Henry Wellcome, a pharmaceutical tycoon in the late 19th and early 20th centuries.
When he died in 1936 at the age of 83, he had gathered some 1 million objects, The New York Times said Wednesday.
James Watson, the Nobel prize winner scientist who co-discovered the structure of DNA was at the opening this week, The Guardian newspaper said.
Where else can you browse the more than 3 billion letters of the human genome, see one of the robots that helped to sequence it and contemplate the reactions of contemporary artists to this major scientific development? In the pioneering Wellcome Collection — how wonderful!, Watson said.
Wellcome Trust director Mark Walport said the museum includes a forum that will host debates encouraging people to really think and be challenged by important contemporary issues around biomedicine.
