The Koechlin family are a French Alsatian family which acquired its wealth in the textile industry and became leading industrialists and politicians of the region.

The Paris–Bordeaux–Paris Trail race of June 1895 is sometimes called the "first motor race", although it did not fit modern competition where the fastest is the winner. It was a win for Émile Levassor, who came first after completing the 1,178km race in 48 hours, almost six hours before second place. However, the official winner was Paul Koechlin, who finished third in his Peugeot, exactly 11 hours slower than Levassor, but the official race regulations had been established for four-seater cars, while Levassor and runner-up Louis Rigoulot were driving two-seater cars.
