Carl Looft (né Knutsen; 9 February 1863 - 10 April 1943) was a Norwegian physician, and among the first pediatricians in Norway.
He was born in Bærum to physician Carl August Knutsen and Margery Henriette Caroline Louise Thaulow, and was a grandson of Heinrich Arnold Thaulow. In 1892 he married Sofie Bolette Gran.
Looft graduated as cand.med. in 1889. His thesis from 1897 was a treatment of mental disability among children. From 1890 to 1940 he practiced as pediatrician in Bergen. In addition to his work as physician, he was responsible for a series of epidemiological investigations among children. Among his conclusions was that appropriate nutrition during pregnancy and infancy was an important factor for the mental development of the children.[1] [2]
