Beck was born in Alsace-Lorraine (then part of German Empire, today it is a part of France) on April 22, 1835, to John Baptist Beck Sr. and Marguerithe Beck, and about 1838 the family emigrated to the United States.[1][2]
In 1849 the young Beck "fought his way into Montana," to an area that is now the city of Bozeman. As a wounded veteran of conflicts with the Sioux in Oregon and Montana, he drew a survivor's pension for fourteen years. He was graduated from F.T. Kefnper's Collegiate School in Booneville, Missouri, in 1853 and then studied at the Massachusetts Institute of Technology, where he earned a degree as a metallurgist in 1870. He also became a lawyer that year.[1]
He visited Los Angeles in 1869 at the behest of the W.H. Workman family and bought a vineyard on San Pedro Street, then moved to the city in 1876. He and Workman had been classmates in Booneville.[1]
Beck was a Presbyterian and a Republican. In 1905 he was supreme commander of the Grand Council of the Legion of the Red Cross and presided at the organization's annual meeting in Atlantic City, New Jersey.
His first wife was Sarah E. Beck, who died in April 1893.[3] He was then married in July 1905[4] to Fidelia A. Anderson, who was at that time the principal of Washington-street School. The wedding of the "well-known school teacher" to Beck, who was "about twenty-five years" her senior, came as a "great surprise," the Los Angeles Times reported, adding: "That the wedding was unexpected in some quarters is indicated by the fact that Miss Anderson was named by the Board of Education only a week or so to continue as principal.[5][6] In those days the policy of the Los Angeles School Board was that married teachers had to resign their positions.[7]
Beck died November 24, 1906 in his Los Angeles home.[2] Masonic services were followed by cremation at Rosedale Cemetery. He left an estate of $26,982,[8] and in November 1909 Beck's sister, Mary A. Chappell, filed suit to have Fidelia Beck removed as trustee of the will because the sister had not received monthly allowances promised to her. Fidelia responded that all the money was gone.[9]
