Early Leaders

September 1903

Ritter, retired newspaper tycoon E.W. Scripps, philanthropist Ellen Browning Scripps, physician Fred Baker, and community leaders charter the Marine Biological Association of San Diego, predecessor of Scripps Institution of Oceanography. Ritter is appointed director with a mandate to perform a biological and hydrographic survey of the coastal waters adjacent to Southern California.


Scripps' First Lab
