Finnish geneticists

Albert de la Chapelle, MD, Ph.D (born 11 February 1933 in Helsinki, Finland) is a Finnish human geneticist, long-time head of Finland's first Department of Medical Genetics at the University of Helsinki, and presently professor of Human Cancer Genetics at Ohio State University. He is best known for his role in the elucidation of the genetics of hereditary colorectal cancer and Lynch syndrome.

Leena Peltonen-Palotie (16 June 1952 – 11 March 2010) was a Finnish geneticist who contributed to the identification of 15 genes for Finnish heritage diseases, including arterial hypertension, schizophrenia, lactose intolerance, arthrosis and multiple sclerosis. She was considered one of the world's leading molecular geneticists.

Eeva Therman (1916–2004) was a Finnish-born American geneticist. She worked to characterize the effects and cytogenetics of trisomy 13 and trisomy 18, two rare and usually fatal genetic disorders caused by an extra copy of chromosome 13 and 18, respectively. Her works include Human Chromosomes: Structure, Behavior, Effects, a textbook on cytogenetics which is in its 4th edition. Her research specialties included X-inactivation in mammals and chromosomal abnormalities in cancer.

Jaakko Arthur Kaprio (born 23 April 1952) is a Finnish human geneticist. He is Professor of Genetic Epidemiology at the Department of Public Health of the University of Helsinki, where he also leads the twin study project. He was director of the Institute for Molecular Medicine Finland (FIMM) starting in October 2015, and ending on 31 January 2018. He formerly held a research professorship funded by the Academy of Finland for five years. He has also served as president of the Society for Research on Nicotine and Tobacco's European Chapter, the International Society for Twin Studies, and the Behavior Genetics Association.

Harry Federley (22 March 1879 – 13 November 1951) was a Finnish zoologist and pioneer of genetics. He conducted hybridization experiments on moths and was later also involved in eugenics in Finland. He was the founder of the department of genetics at the University of Helsinki.

Iiris Hovatta (born 31 December 1970 in Espoo, Finland) is a Finnish geneticist and neuroscientist, specializing in genetics, genomics, behavioral neuroscience, and biological psychiatry. She is professor of behavioral genetics at the University of Helsinki, Finland.
