The Wikipedia article of the day for June 15, 2019 is Adam Eckfeldt.
Adam Eckfeldt (June 15, 1769 – February 6, 1852) was the second chief coiner of the United States Mint. His father owned a large smithy and involved himself in early attempts at American coinage. Eckfeldt built early presses for the Mint, engraved some of its early dies, and was responsible for some designs of early American copper pieces, as well as the 1792 half disme, which some authorities consider the first United States coin. He was appointed assistant coiner of the Mint in 1796, and became chief coiner after his predecessor's death in 1814. During Eckfeldt's tenure, the Philadelphia Mint moved to new premises and expanded its operations. Setting aside unusual coins that were brought in as bullion, he started the Mint's coin cabinet, which evolved into the National Numismatic Collection. Despite his 1839 retirement, Eckfeldt continued performing the duties of chief coiner until his death, though his successor, Franklin Peale, bore the title.
