English: This historic photograph depicted Centers for Disease Control (CDC) laboratorian George Gorman at left, along side Dr. Jim Feeley, while they were examining culture plates, i.e., Petri dishes, upon which the first environmental isolates of Legionella pneumophils had been grown.

Dr. Feely and Mr. Gorman were the creators of a non-selective medium known as “F-G (Feely-Gorman) medium”, which was used to harvest cultures of L. pneumophila early on in the identification of this bacteria, as the pathogen responsible for causing what came to be known as Legionnaires’ disease. In the photograph, Mr. Gorman can be seen working under a negatively-pressurized ventilation hood, while Dr. Feely was checking the plates under a binocular microscope.
