Lars Magnus Ericsson, a Swedish inventor and businessman, opened his small workshop for the manufacture of mathematical and physics instruments, as well as the repair of telegraphy equipment, in 1876. A couple of years later, he began to manufacture high-quality telephone sets, with which he was projected to the world markets. In Mexico, his company, Telefonaktiebolaget LM Ericsson & Co, obtained the service concession in 1894, but the commercial registration of his name and the beginning of its work were made until 1904, when Alex Bostrom asked the government for its respective authorization.
