1877 – Born on October 21st in Halifax, Nova Scotia. Canadian-born American bacteriologist whose research helped ascertain that DNA is the substance responsible for heredity, thus laying the foundation for the new science of molecular genetics.

1887 – He went to New York City when his clergyman father began missionary work in the Bowery.
