Pierre René Jean Baptiste Henri Brocard (French pronunciation: [pjɛʁ ʁəne ʒɑ̃ batist ɑ̃ʁi bʁɔkaʁ]; 12 May 1845 – 16 January 1922) was a French meteorologist and mathematician, in particular a geometer.[1] 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.[2]
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.[3] He was awarded the Ordre des Palmes Académiques, and was an officer of the Légion d'honneur.[4]
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.[1]
