General view of an unidentified man, presumably a laboratory assistant, seated at a work bench with assorted scientific equipment and glassware. While the setting of this photograph is also unidentified, the photo was donated along with other materials related to the Hospital of the Rockefeller Institute for Medical Research (H.R.I.M.R.) and may depict a laboratory at that facility. However, there is no contextual information directly linking this photo to the H.R.I.M.R.
