Catalog type History
Provenance Dr. Wilton Earle pioneered processes for growing cells in culture during the 1930-1950s to study how cells become cancerous. He developed a three-dimensional culture containing multi-layered cellophane sheets or glass helices for growing clones of a single cell. From "Dr. Earle, World Expert on Tissue Culture, Dies. Served NCI Since 1937," NIH Record, June 16, 1964, page 7: "Dr. Earle made many significant contributiions to the development of tissue culture science and technology. His contributions were outstanding in improving tissue culture techniques and in advancing the purposes for which long-term, large-scale cell culture could be used in medical research, specifically in cancer research. He was a pioneer in demonstrating that carcinogenesis occurs in vitro."
