Friedrich Leibniz (or Leibnütz; 1597–1652) was a Lutheran lawyer and a notary, registrar and professor of moral philosophy within Leipzig University. He was the father of Gottfried Leibniz.
He completed his master's degree at the University of Leipzig during 1622 and became an actuary in administration at the University. His first marriage in 1625 produced a son, Johann Friedrich, and a daughter, Anna Rosina. He was elected to the chair in moral philosophy at Leipzig in 1640. A childless marriage to a second wife ended with her death 1643. A subsequent 1644 marriage to Catharina Schmuck, a daughter of a well known lawyer (or professor of law) produced a son, the polymath Gottfried Wilhelm Leibniz.
