• Referred to as the "Father of Nematology in the United States".

• He identified over 1000 species of nematodes, including animal parasitic, plant parasitic, free-living, fresh water, and marine forms.

• He made many innovative technical contributions to Nematology, including: (a) fixation and preservation methods; (b) the Cobb metal mounting slide; (c) adaptation of photographic equipment, light filters, and improvements in the camera lucida for microscopic use with nematodes; and (d) development of the first flotation device for removing nematodes from soil.
