Fredrik Vogt (23 December 1892 – 26 January 1970) was a Norwegian engineer and civil servant. In the 1930s he was a professor and rector at the Norwegian Institute of Technology (Norwegian abbreviation NTH). As the first director general of the Norwegian Water Resources and Energy Agency, he played a central role in developing the hydroelectric power capacity in Norway after the Second World War.
Vogt was born in Kristiania; a son of professor of metallurgy and geology Johan Herman Lie Vogt and Martha Johanne Abigael Kinck. He was a brother of geologist Thorolf Vogt, economist Johan Vogt and newspaper editor and politician Jørgen Vogt. In 1916 he married Signe Fjalstad, a sister of jurist and politician Olaf Fjalstad. He was a brother-in-law of actor Martin Linge and physician Odd Havrevold, who both were married to his sister Margit. He died in Oslo in January 1970.
Vogt graduated as construction engineer from the Norwegian Institute of Technology in 1914, and as dr. techn. in 1924. His thesis, Berechnung und Konstruktion des Wasserschlosses, was published in Germany. He was the first doctorate from the NTH. From 1914 to 1918 he worked as engineer for Kincks Vandbygningskontor. From 1918 to 1922 he constructed the Skarfjord hydroelectric plant in Northern Norway. He was appointed at the Norwegian Institute of Technology from 1922, as professor in mechanics from 1931. He published nearly fifty scientific papers in various journals. In 1936 he was elected rector of the institute.
As rector during the German invasion of Norway, and the subsequent occupation, Vogt faced various challenges. He was re-elected as rector in May 1940, but resigned from his position in September 1941, and moved to Oslo. In January 1943 he skied to Sweden, and was immediately brought to England. In London he worked for the Norwegian government in exile. From the summer of 1943 he chaired a governmental industrial committee.
