He presented the principle the synchronous motors (1883), and designed electric generators with better efficiency. He also studied condensers and the phenomena of residual load. In his earlier career, he became (1872) engineering manager of Chance Brothers and Co., a glass manufacturer in Birmingham, where he studied lighthouse illumination, improving efficiency with flashing groups of lights.

  • 1837: Peter Dirichlet presented his first analytic number theory paper at a meeting of the Berlin Academy of Sciences. He proved the fundamental theorem that bears his name: Every arithmetical sequence an + b, n = 0, 1, 2, ... of integers, where a and b are relatively prime, contains infinitely many primes.
