Julius Richard Petri (1852-1921) is credited with inventing the petri dish in 1877. Mr. Petri who was growing bacteria in slant cultures needed sub-culturing on a solid surface to stabilize and segregate bacteria slant cultures. Slant or liquid culture is the first step in the recovery of microorganisms. Subculture from Slant or liquid culture to solid culture is the stabilizing and segregating step necessary to subculture for identification.

Dr. Jonathan N. Roth invented Easygel ® which is a slant/liquid and solid culture media meeting the requirements for optimum recovery and segregation of microorganisms for identification.

In the late 1970s, Dr. Jonathan N. Roth began work on a temperature-independent gelling agent to be used in place of agar-agar, the "vegetable gelatin" upon which the growth of microorganisms on solid media depended. Dr. Roth's work with low methoxyl pectins as agar substitutes resulted in the patented product, Easygel ® .
