Weydmann was educated in Basel. In Amsterdam he witnessed the establishment of the Algemeene Doopsgezinde Sociëteit (1811). The Mennonite professors at Amsterdam at that time were Gerrit Hesselink, who was a natural scientist rather than a theologian, and Rinse Koopmans, who stressed the divine authority of revealed doctrine. In 1812 Weydmann wrote a paper on the "Excellence of Mathematics," in 1814 a paper on "Baptism, as It Was Practiced by the Apostles and the Superstitious Practices That Were Later Connected with It," and another work about the "Authenticity of the Books of the New Testament." He studied briefly then at the University of Berlin and in 1816 became the minister in Zutphen and after that in Friedrichstadt.
After several months in Krefeld he received a call to the Kriegsheim congregation and then in 1820 a call to Monsheim. Here he witnessed the establishment of the Palatine-Hessian Conference (1824), which was accompanied by an increased interest in missions. He was the first trained minister in the Palatinate and rendered valuable service there in the matter of their hymnal (1832) and their catechism (1836).
In 1836-1866 he served in his home congregation of Krefeld. Here too he did some literary work. In 1850 he published the book Luther, ein Charakter und Spiegelbild für unsere Zeit, and in 1852 Christliche Lehre, zunächst zum Gebrauch der Taufgesinnten in Deutschland.
