British mathematician Charlotte Scott was born #OTD in 1858.
Her research focused on algebraic geometry, a field dealing with solutions to systems of polynomial equations. Notable works include her paper on binary forms and her research on the properties of algebraic curves. She co-authored "An Introductory Account of Certain Modern Ideas and Methods in Plane Analytical Geometry," which became a widely used textbook. She was awarded an honorary degree by the UPenn in 1906.
Irish mathematician Alicia Boole Stott was born #OTD in 1860.

She extensively used Schläfli symbols to categorize and describe polytopes. Later in life, Alicia worked with Harold Coxeter and their collaboration furthered the understanding of regular polytopes and three-dimensional projections of four-dimensional figures.

English mathematician and computer scientist Alan Turing died #OTD in 1954.
During World War II, he played a crucial role in deciphering the Enigma code used by the German military, significantly contributing to the Allied war effort. In his paper "Computing Machinery and Intelligence," he proposed the famous Turing Test as a criterion for determining whether a machine can exhibit intelligent behavior indistinguishable from that of a human.

He formulated Cassini’s Law, describing the rotational behavior of the Moon, which was crucial for understanding the Moon's synchronous rotation with the Earth. He was involved in measuring the meridian arc of Paris, contributing to the accurate determination of the shape of the Earth.
Greenlandic-Danish polar explorer and anthropologist Knud Rasmussen was born #OTD in 1879.
He went on his first expedition in 1902–1904, known as The Danish Literary Expedition, with Jørgen Brønlund, Harald Moltke and Ludvig Mylius-Erichsen, to examine Inuit culture and traditions.
