Research at Rutgers
Schatz worked in Waksman’s programme investigating soil microorganisms that produced antibacterial substances. In 1943 he isolated streptomycin from cultures of Streptomyces griseus. The Nobel organization’s historical account explicitly identifies his contribution to this isolation.
A collaborative report
The early streptomycin paper named Schatz, Elizabeth Bugie and Waksman as its authors. Their research connected microbial cultivation and screening with tests of antibacterial activity. Subsequent drug development and clinical investigation involved additional researchers and institutions.
Co-discovery and royalties
Schatz and Waksman jointly applied for a streptomycin patent. Schatz later sued Waksman and the associated Rutgers foundation over recognition and royalties. Rutgers’s archive description records a settlement recognizing Schatz as a co-discoverer and allocating him a share of royalties.
