Canadian American molecular biologist (1939-2022)
Sidney Altman was a Canadian American molecular biologist who discovered that RNA molecules can act as catalysts to speed up chemical reactions in cells, a finding that challenged the previous understanding that only proteins could perform this function. This discovery, which earned him the Nobel Prize in Chemistry in 1989, fundamentally changed how scientists think about the role of RNA in living organisms.
