1889 – 1938
Who was Calvin Bridges?
Calvin Blackman Bridges was an American scientist, known for his contributions to the field of genetics. Along with Alfred Sturtevant and H.J. Muller, Bridges was part of the famous fly room of Thomas Hunt Morgan at Columbia University.
His work with sex linked traits in the fruit fly Drosophila melanogaster suggested that chromosomes contained genes. Later Nettie Maria Stevens was able to prove this hypothesis by examining the chromosomes of the fruit flies. Bridges wrote a couple of papers presenting the proof. He thanked her as "Miss Stevens" without stating what her contribution was nor referring to her PhD.
Bridges' best-known contribution among Drosophila researchers is his observation and documentation of the polytene chromosomes found in larval salivary gland cells. The banding patterns of these chromosomes are still used as genetic landmarks even by contemporary researchers.
