1889 – Bridges was born on the 11th of January in Schuyler Falls, New York.

1916 – Bridges wrote a masterful Ph.D. thesis on "Non-disjunction as proof of the chromosome theory of heredity." It appeared as the first paper in the first issue of the journal Genetics.

         – His work with sex linked traits in the fruit fly Drosophila melanogaster suggested that chromosomes contained genes. Later Nettie Maria Stephens was able to prove this hypothesis by examining the chromosomes of the fruit flies.

         – Bridges’ best-known contribution among Drosophila researchers is his observation and documentation of the polytene chromosomes found in larval salivary gland cells.

1938 – He died on the 27th of December in Los Angeles, California.
