It was here that Gottlieb Daimler met and grew to appreciate the abilities of Maybach, twelve years his junior. The pair would remain friends and partners until Daimler’s death. Maybach followed Daimler, for example, to the Deutz gas engine factory in Cologne, where Daimler became Technical Director in 1872. Maybach’s career advanced rapidly at Deutz, and he was appointed chief engineering designer in 1873. Privately, too, the two men’s lives were closely intertwined, since Maybach married a friend of Emma Daimler, Gottlieb Daimler’s wife, in 1878.
