Louis Jean Baptiste Bergeron (10 March 1876 – 23 February 1948) was a French entrepreneur, engineer and inventor.
In 1900, he started work as an electrical engineer and made a career in the Farcot company in St Ouen, a factory specializing in steam engines and high-power electrical machines.
Following an amicable split with Beaudrey, the company was renamed Bergeron S.A., which is now a part of Alstom.
In electrical engineering, application of so-called "Bergeron equations" allows the calculation of travelling wave phenomena in "long" conductors using numerical analysis.
Hermann W. Dommel used these "Bergeron equations" in the EMTP (electromagnetic transient program) software in the late 1960s.
