Alfred G. Mayer (Alfred Goldsborough Mayor; April 16, 1868 – June 24, 1922) was an American marine biologist and zoologist, whose fascination with medusae (jellyfish) marked a turning point for biology. Despite Mayor's interest in the sea, his first voyage began during his twenty-fourth year of life.[1] Because of his German 'heritage', "[...]he altered it (his last name) to "Mayor" in order to dissociate himself from his Germanic roots".[1] Mayor is also greatly known for his many publications and papers in which he wrote about topics ranging from physics to hunting and fishing.
