Henri Brocard

Who was Henri Brocard?

Pierre René Jean Baptiste Henri Brocard was a French meteorologist and mathematician, in particular a geometer. His best-known achievement is the invention and discovery of the properties of the Brocard points, the Brocard circle, and the Brocard triangle, all bearing his name.

Contemporary mathematician Nathan Court wrote that he, along with Émile Lemoine and Joseph Neuberg, was one of the three co-founders of modern triangle geometry. He is listed as an Emeritus at the International Academy of Science, was awarded the Ordre des Palmes Académiques, and was an officer of the Légion d'honneur.

He spent most of his life studying meteorology as an officer in the French Navy, but seems to have made no notable original contributions to the subject.
