From the LCMS website:

Carl Ferdinand Wilhelm Walther (1811-87), the father of The Lutheran Church–Missouri Synod, served as its first president from 1847 to 1850 and then again from 1864 to 1878. In 1839 he emigrated from Saxony, Germany, with other Lutherans, who settled in Missouri. He served as pastor of several congregations in St. Louis, founded Concordia Seminary, and in 1847 was instrumental in the formation of the LCMS (then called the Evangelical Lutheran Synod of Missouri, Ohio, and Other States). Walther worked tirelessly to promote confessional Lutheran teaching and doctrinal agreement among all Lutherans in the United States. He was a prolific writer and speaker. Among his most influential works are Church and Ministry and The Proper Distinction between Law and Gospel.
