Walter Nelson-Rees

Walter Nelson-Rees (11 January 1929 – 23 January 2009) was a cell culture worker and cytogeneticist who helped expose the problem of cross-contamination of cell lines. He used chromosome banding to show that many immortal cell lines, previously thought to be unique, were actually HeLa cell lines. The HeLa cells had contaminated and overgrown the other cell lines.[1][2]
