Ernst Alfred Bostrom (1855-1923) was a Swedish immigrant who worked as a machinist for the telephone company in Atlanta, Georgia. After enrolling with the International Correspondence School, he advanced to foreman and then to superintendent. He formed the Bostrom-Brady Manufacturing Co. in 1901 and began manufacturing a simple and inexpensive farm level of his own design. The Bostrom Convertible Level followed some years later, and could be used as either a transit or a level. Alfred Droke used this example while working with the Civilian Conservation Corps during the 1930s. The inscription reads "MFD. BY BOSTROM-BRADY MFG. CO. ATLANTA, GA." That on the box reads "BOSTROM SURVEYING INSTRUMENTS MODEL NO. 5 SERIAL NO. 47 BOSTROM-BRADY MFG. CO. ATLANTA, GA. U.S.A."
