Veikko Aleksanteri Heiskanen (V. A. Heiskanen; also spelled Weikko Aleksanteri (or W. A.) Heiskanen; 23 July 1895 – 23 October 1971) was a Finnish geodesist and geophysicist. ^{[1] [2]} He was known for his refinement of George Biddell Airy and John Henry Pratt's theories of isostasy into his own, the Heiskanen hypothesis. ^{[3] [4]} With Felix Andries Vening Meinesz, he wrote the textbook The Earth and its Gravity Field (1958), ^{[5] [6]} and in 1960 a paper by Heiskanen, "The latest achievements of physical geodesy" was discussed in the scientific literature. ^[7] With Helmut Moritz, Heiskanen wrote the textbook Physical Geodesy (1967), which became a standard text the field of geodesy and for the study of the geoid. ^{[8] [9]} Heiskanen's doctoral students include Ivan I. Mueller.

Born c. 23 July 1895 ^[a] in Kangaslampi, Finland, he grew up on a small farm. He attended the University of Helsinki and in three years received a Candidate in Philosophy degree (some texts state he received the Master of Science degree). ^{[10] [11]} In 1927 he received a Doctor of Philosophy degree from the university. ^[12]

The Kaarina and Weikko A. Heiskanen Fund endows the Kaarina and Weikko A. Heiskanen Award, ^[13] which is awarded annually by the Ohio State University. ^[14] The university hosted the Weikko A. Heiskanen Symposium in Geodesy in 2002 to celebrate that geodesy had been studied at Ohio State for 50 years. ^[15]

A book, Surveyor of the Globe, was written as a biography of Heiskanen by Juhani A. Kakkuri [ fi] and published in 2008 and 2017. ^{[16] [17]}
