Year 1712 (MDCCXII) was a leap year starting on Friday (link will display the full calendar) of the Gregorian calendar and a leap year starting on Tuesday of the 11-day slower Julian calendar. In the Swedish calendar it began as a leap year starting on Monday and remained so until Thursday, February 29. By adding a second leap day (Friday, February 30) Sweden reverted to the Julian calendar and the rest of the year (from Saturday, March 1) was in sync with the Julian calendar. Sweden finally made the switch from the Julian to the Gregorian calendar in 1753.

Willard Mitt Romney (born March 12, 1947) is an American businessman and the presumptive nominee of the Republican Party for President of the United States in the 2012 election. He was the 70th Governor of Massachusetts (2003–07).

The son of Lenore and George W. Romney (Governor of Michigan, 1963–69), he was raised in Bloomfield Hills, Michigan. In 1966, after one year at Stanford University, he left the United States to spend thirty months in France as a Mormon missionary. In 1969, he married Ann Davies, and the couple had five children together. In 1971, he earned a Bachelor of Arts degree in English from Brigham Young University and, in 1975, a joint Juris Doctor and Master of Business Administration from Harvard University as a Baker Scholar. He entered the management consulting industry, which in 1977, led to a position at Bain & Company. Later serving as Chief Executive Officer, he helped bring the company out of financial crisis. In 1984, he co-founded the spin-off Bain Capital, a private equity investment firm that became highly profitable and one of the largest such firms in the nation. His net worth is estimated at $190–250 million, wealth that has helped fund his political campaigns. Active in The Church of Jesus Christ of Latter-day Saints, he served as Ward Bishop and later Stake President in his area near Boston. He ran as the Republican candidate in the 1994 U.S. Senate election in Massachusetts, losing to long-time incumbent Ted Kennedy. In 1999, he was hired as President and CEO of the Salt Lake Organizing Committee for the 2002 Winter Olympics and Paralympics; and he helped turn the fiscally troubled games into a success.

Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was a King in Prussia (1740–1772) and a King of Prussia (1772–1786) from the Hohenzollern dynasty. In his role as a prince-elector of the Holy Roman Empire, he was also Elector of Brandenburg. He was in personal union the sovereign prince of the Principality of Neuchâtel. He became known as Frederick the Great (Friedrich der Große) and was named Der Alte Fritz ("Old Fritz").

Interested primarily in music and philosophy and not the arts of war during his youth, Frederick unsuccessfully attempted to flee from his authoritarian father, Frederick William I, with childhood friend Hans Hermann von Katte, whose execution he was forced to watch after they were captured. Upon ascending to the Prussian throne, he attacked Austria and claimed Silesia during the Silesian Wars, winning military acclaim for himself and Prussia. Near the end of his life, Frederick physically connected most of his realm by conquering Polish territories in the First Partition of Poland.

Friedrich Wilhelm Zachow or Zachau (14 November 1663, Leipzig – 7 August 1712, Halle) was a German musician and composer of vocal and keyboard music.

Zachow probably received his training from his father, the piper Heinrich Zachow, one of Leipzig's town musicians in the Alta capella, and maybe from Johann Schelle, a leading German composer, when the family moved to Eilenburg. As Kantor and organist of Halle's Market Church in 1684 he succeeded Samuel Ebart. During his time at Halle he became particularly renowned as a composer of dramatic cantatas. In 1695 he was criticized by the pietists because of his excessive long and elaborate music, that could be only appreciated by cantors and organists. Zachow was influenced by Johann Theile in Merseburg and the poetry of Erdmann Neumeister, pastor in the nearby Weissenfels, and his criticism on pietism.

Zachow was the teacher of Gottfried Kirchhoff, Johann Philipp Krieger and Johann Gotthilf Ziegler, but is best remembered as George Frideric Handel's first music teacher. He taught Handel how to play the violin, organ, harpsichord, and oboe as well as counterpoint. Zachow's teaching was so effective, that in 1702 at the age of seventeen, Handel accepted a position as organist at the former Dom in Halle. It is said that after Zachow died in 1712, Handel became a benefactor to his widow and children in gratitude for his teacher's instruction. In 1713 J.S. Bach was invited as Zachow's successor.
