The American Type Culture Collection was suggested by many respondents as a suitable place to store and preserve genetically valuable microbiological material. Since J] represent our Society on the ATCC Board, I have been asked to write to a few colleagues to request suggestions for a personnel opening at the new ATCC, now located in Rockville Park near the NIH buildings in an entirely new structure. The Director, Dr. William A. Clark, has sent the enclosed description of the position. Some independent research would be possible; the Collection plans to combine its service functions with a research program oriented toward various problems including cell characterization, preservation of cultures, and genetic and taxonomic identification. Dr. Lessel is the person in charge of bacteria. Possible interests of a candidate would be computer or Adansonian taxonomy, hereditary aspects of nutrition, interspecific crossing, nucleic acid homologies, genetic criteria for classification, evolutionary relationships, etc., all in relation to bacteria. If you have any knowledge of postdoctoral fellows, or younger geneticists who would be interested, please let me know. The salary is open, with the aim being to provide a scale comparing well with employment at the NIH and similar institutions. The ATCC is a private non-profit organization well-supported by both NSF and USPHS.
