Hugo Gernsbacher was born in Luxembourg in 1884. He received a technical education; his special interest was telephone and electrical communications equipment. By the end of his life, he would have 80 patents. He came to America in 1904, and began a company called the Electric Importing Company, which was the forerunner of companies like Radio Shack, selling radio building equipment by mail. The catalog of this company became Modern Electrics, a magazine that he edited and published. In 1926 he started Amazing Stories, perhaps the most famous of the early sf magazines. He died in 1967.
