Émile Lemoine
Émile Lemoine was a French civil engineer and mathematician, a geometer in particular. He was educated at a variety of institutions, including the Prytanée National Militaire and, most notably, the École Polytechnique. Lemoine taught as a private tutor for a short period after his graduation from the latter school. Lemoine is best known for his proof of the existence of the Lemoine point (or the symmedian point) of a triangle. Other mathematical work includes a system he called Géométrographie and a method which related algebraic expressions to geometric objects. He has been called a co-founder of modern triangle geometry, as many of its characteristics are present in his work. For most of his life, Lemoine was a professor of mathematics at the École Polytechnique. Later, he worked as a civil engineer in Paris, and took an amateur's interest in music. During his tenure at the École Polytechnique and as a civil engineer, Lemoine published several papers on mathematics, most of which are included in a fourteen-page section in Nathan Court's College Geometry. Additionally, he founded a mathematical journal: L'intermédiaire des mathématiciens. (more...)

Portsmouth Square, San Francisco, 1851

An 1851 daguerreotype of Portsmouth Square, San Francisco, California. Now a one-block square in Chinatown, it is located on the site of the first public square established in Yerba Buena, the Mexican community that became San Francisco. It is named after the USS Portsmouth, which raised the American flag here at the onset of the Mexican–American War.
