Frederick III (17 January 1463 – 5 May 1525), also known as Frederick the Wise (German "Friedrich der Weise"), was Elector of Saxony (from the House of Wettin) from 1486-1525.  Frederick was the son of Ernest, Elector of Saxony and his wife Elisabeth, daughter of Albert III, Duke of Bavaria.  He is notable as being one of the most powerful early defenders of Martin Luther, Lutheranism and the Protestant Reformation although he had little personal contact with Luther himself.  Fredericks' treasurer Degenhart Pfaffinger (Pfaffinger being a German dynasty), spoke on behalf of him to Martin Luther.  Pfaffinger supported Frederick since the joint pilgrimage to the holy land.  He is considered to have remained a Roman Catholic all his life, yet gradually inclining toward doctrines of the Reformation. The Capitulation of Wittenberg (German: "Wittenberger Kapitulation" ) was a treaty in 1547 by which John Frederick I, Elector of Saxony, was compelled to resign the electoral dignity.

John Frederick Steinbruck (October 5, 1930 – March 1, 2015) is an ordained Lutheran minister who served for 28 years (1970–1997) as the senior pastor of Luther Place Memorial Church in Washington, D.C. Luther Place is an historic, red-stone church located at Thomas Circle, 1226 Vermont Avenue, N.W., in the heart of Washington's red-light district.  Less than a mile from the White House, the church sits between the symbols of world power and some of the nation's worst urban blight.  As spiritual leader of Luther Place and what is now known as N Street Village, a diverse consortium of shelters and services for homeless women and their families, Steinbruck became an articulate and passionate preacher of the Social Gospel and a leading voice locally and nationally for the homeless, Central American refugees, and the victims of persecution and prejudice. Paul Luther (28 January 1533 – 8 March 1593) was a German physician, medical chemist, and alchemist.

He taught alchemy to Anne of Denmark. The Luther seal or Luther rose is a widely recognized symbol for Lutheranism.  It was the seal that was designed for Martin Luther at the behest of John Frederick of Saxony in 1530, while Luther was staying at the Coburg Fortress during the Diet of Augsburg.  Lazarus Spengler, to whom Luther wrote his interpretation below, sent Luther a drawing of this seal.  Luther saw it as a compendium or expression of his theology and faith, which he used to authorize his correspondence.  Luther informed Philipp Melanchthon on September 15, 1530, that the Prince had personally visited him in the Coburg fortress and presented him with a signet ring, presumably displaying the seal. John Frederick Herring Sr. (12 September 1795 – 23 September 1865), also known as John Frederick Herring I, was a painter, sign maker and coachman in Victorian England.
