Adriaan Hendrik Johan Prins, generally known as A. H. J. Prins (1921, Harderwijk, Gelderland – 11 February 2000) was a Dutch Africanist and maritime anthropologist.

He was a recipient of many research grants and fellowships (UNESCO, Ford Foundation, the Netherlands Organization for Pure Research, etc.), Prins was frequently consulted by the Dutch government and royal court, who valued his wealth of knowledge about the peoples and cultures of Africa and the Middle East.

In addition to scores of encyclopedia entries and dozens of scholarly articles in a wide range of international journals such as Anthropos, Man, Human Organization, and The Mariner’s Mirror, Prins regularly published in Dutch newspapers and magazines. Moreover, he illustrated many of his books and articles with his own ethnographic photographs, sketches, and pen drawings.

Early life and education
Prins studied social geography and ethnology at the University of Utrecht under Prof. Dr. Henri Th. Fischer.

In 1943, the German occupying forces ordered Dutch students and faculty to sign a "loyalty declaration". Like many others, Prins refused and joined the resistance movement, ultimately becoming chief of intelligence in the VIth Brigade (Veluwe). He was known as "Peter", his nom de guerre. Following the 1944 Battle of Arnhem, he was incorporated into the British Intelligence Section (MI9), a department of the War Office tasked with aiding resistance fighters in enemy occupied territories.  Given the rank of first lieutenant, he served in the Intelligence Branch of the General Staff of the 21st Army Group, commanded by Montgomery.

After demobilization in 1945, he resumed graduate studies at Utrecht. A year later, having acquired his doctoraal degree, he became a research assistant at Utrecht's Institute of Ethnology under Fischer. In 1947, he received a fellowship at the London School of Economics for social anthropology training under Raymond Firth, Siegfried Nadel, and Audrey Richards. Then, equipped with language training in Swahili, he travelled to Kenya as a British Colonial Fellow for ethnographic research in the Teita Hills. Guided by Senior District Commissioner Harold E. Lambert, a Cambridge University-trained anthropologist and linguist specialized in the Swahili and Kikuyu languages, Prins began his fieldwork. Later, he dedicated one of his books to Lambert. Although Prins focused initially on British anthropological topics, such as kinship and social structure, his enduring interest concerned the maritime history and cultural ecology of seafaring peoples.

Career
In 1951, two years before earning his PhD from Utrecht U, Prins was hired as the first anthropologist at the University of Groningen, where he later became the founding director of the Institute of Cultural Anthropology. Although he lectured at many institutions in Europe, East Africa, and the Middle East, he remained there until his retirement in 1984.

Fieldwork
A committed fieldworker, Prins made numerous journeys abroad during and after his tenure in Groningen. In 1957, he began studying dhows, the lateen-rigged sailing ships of the Indian Ocean and the way in which they operate, first in the Persian Gulf, then on the coast of Zanzibar, Kenya and Tanganyika (1957, 1965–66, 1967, 1968, 1970, 1971). Other projects involved research in Ethiopia (1954–55), Iraq (1957), Iran (1959), the Persian Gulf (1970, 1973), Syria and Turkey (1961–62, 1970), South Arabia (1970, 1973), Zambia (1972, 1974). One of the founders of the Arctic Centre at Groningen University, he made annual research trips to northern Scandinavia from 1968 to 1992, and beginning in 1970 traveled to Greece and made frequent journeys to the Mediterranean island of Malta.

Retirement
After his retirement in 1984, the Dutch government restructured higher education and terminated the anthropological institute at Groningen University. As an Emeritus Professor, Prins continued various maritime and cultural historical research projects. He died on 11 February 2000, after five years of illness, the result of a debilitating stroke. Buried in Noordlaren near "Huis ter Aa," his family home in the old rural village of Glimmen south of Groningen City, he was survived by his wife Ita (P.A.C. Prins-Poorter, 1921–2016), nine children, and sixteen grandchildren.
