Heinrich Brandt (November 8, 1886 - October 9, 1954) was a mathematician who studied at the University of Göttingen, and from 1910 to 1913 at the University of Strasbourg. In 1912 he attained his doctorate; he was a student of Heinrich Weber.
From 1913 he was assistant to the Technische Hochschule at Karlsruhe. He taught geometry and applied mathematics from 1921 to the Technische Hochschule at Aachen. From 1930 he was the chair for mathematics at the University of Halle.
A Brandt matrix is a computational way of describing the Hecke operator action on theta series as modular forms. The theory was developed in part by Brandt's student Martin Eichler. It offers an algorithmic approach for machine computation (in that theta series span spaces of modular forms); the theory now considered by means of Brandt modules.
