Chargaff returned to Europe, where he lived from 1930 to 1934, serving first as the assistant in charge of chemistry for the department of [[bacteriology]] and [[public health]] at the [[University of Berlin]] (1930–1933) and then, being forced to resign his position in Germany as a result of the Nazi policies against Jews, as a research associate at the [[Pasteur Institute]] in [[Paris]] (1933–1934). ==Columbia University== Chargaff immigrated to [[Manhattan]], [[New York City]] in 1935,<ref name=ssc>{{Cite journal|url=https://www.jstor.org/stable/1558287|jstor=1558287|title=Erwin Chargaff, 11 August 1905 · 20 June 2002|last1=Cohen|first1=Seymour S.|journal=Proceedings of the American Philosophical Society|year=2004|volume=148|issue=2|pages=222–228}}</ref> taking a position as a research associate in the department of biochemistry at [[Columbia University]], where he spent most of his professional career. Chargaff became an [[assistant professor]] in 1938 and a professor in 1952. After serving as department chair from 1970 to 1974, Chargaff retired as professor [[emeritus]]. After his retirement as professor emeritus, Chargaff moved his lab to [[Roosevelt Hospital]], where he continued to work until his retirement in 1992.{{citation needed|date=December 2011}} He became an American citizen in 1940. During his time at Columbia, Chargaff published numerous scientific papers, dealing primarily with the study of [[nucleic acids]] such as [[DNA]] using [[chromatographic]] techniques. He became interested in [[DNA]] in 1944 after [[Oswald Avery]] [[Avery-MacLeod-McCarty experiment|identified]] the molecule as the basis of [[heredity]].<ref name=avery44>{{cite journal|last1=Avery|first1=Oswald T.|last2=MacLeod|first2=Colin M.|last3=McCarty|first3=Maclyn|title=Studies on the Chemical Nature of the Substance Inducing Transformation of Pneumococcal Types – Induction of Transformation by a Desoxyribonucleic Acid Fraction Isolated from Pneumococcus Type III|journal=Journal of Experimental Medicine|date=February 1, 1944|volume=79|issue=2|pages=137–158|pmid=19871359|pmc=2135445|doi=10.1084/jem.79.2.137}}</ref><ref name=weintraub06/><ref name="mccarty03">{{cite journal |doi=10.1038/nature01398|title=Discovering genes are made of DNA |year=2003 |last1=McCarty |first1=Maclyn |journal=Nature |volume=421 |issue=6921 |page=406 |pmid=12540908 |bibcode=2003Natur.421..406M|s2cid=4335285|doi-access=free }}</ref> [[Seymour S.

The first and best known achievement was to show that in natural [[DNA]] the number of [[guanine]] units equals the number of [[cytosine]] units and the number of [[adenine]] units equals the number of [[thymine]] units. In human DNA, for example, the four bases are present in these percentages: A=30.9% and T=29.4%; G=19.9% and C=19.8%. This strongly hinted towards the [[base pair]] makeup of the DNA, although Chargaff did not explicitly state this connection himself. For this research, Chargaff is credited with disproving the [[tetranucleotide hypothesis]]<ref>{{cite journal | title = Yeast nucleic acid | last= Levine | first = P.A. | journal = Biochem. Z. | date = 1909 | volume= 17 | pages= 120–131 }}</ref> ([[Phoebus Levene]]'s widely accepted hypothesis that DNA was composed of a large number of repeats of GACT). Most researchers had previously assumed that deviations from equimolar base ratios (G = A = C = T) were due to experimental error, but Chargaff documented that the variation was real, with [C + G] typically being slightly less abundant. He did his experiments with the newly developed [[paper chromatography]] and [[ultraviolet spectrophotometer]]. Chargaff met [[Francis Crick]] and [[James D. Watson]] at [[Cambridge]] in 1952, and, despite not getting along with them personally,<ref>{{cite book |title=Landmark Experiments in Molecular Biology|author=Michael Fry|date=2016|publisher=Academic Press|page=220|isbn=978-0-12-802074-6}}</ref> he explained his findings to them. Chargaff's research would later help the Watson and Crick laboratory team to deduce the [[double helical]] structure of DNA. The second of Chargaff's rules is that the composition of DNA varies from one species to another, in particular in the relative amounts of A, G, T, and C bases. Such evidence of molecular diversity, which had been presumed absent from DNA, made DNA a more credible candidate for the [[genetic material]] than [[protein]].<ref name="baianu10">{{cite book |last1=Baianu |first1=I.C. |title=Mathematical and Theoretical Biology.
