Casimir Pulaski, or Kazimierz Pułaski in Polish (Polish pronunciation: [kaʑiˈmʲɛʂ puˈwaski] ( listen); full name in Polish: Kazimierz Michał Wacław Wiktor Pułaski) of Ślepowron coat-of-arms (March 6, 1745 – October 11, 1779) was a Polish soldier, nobleman, and politician who has been called "the father of American cavalry".

A member of the Polish landed nobility, Pulaski was a military commander for the Bar Confederation and fought against Russian domination of the Polish–Lithuanian Commonwealth. When this uprising failed, he emigrated to North America as a soldier of fortune. During the American Revolutionary War, he saved the life of George Washington and became a general in the Continental Army. He died of wounds suffered in the Battle of Savannah. Pulaski is one of only seven people to be awarded honorary United States citizenship.

Pulaski was born on March 6, 1745 in the now-nonexistent Pulaski manor house, located near the present address 53 Nowy Świat St. near Warecka St. in Warsaw, Poland (the date and place have been erroneously reported in some older sources). His father, Józef Pułaski, was a well-known lawyer - the Advocatus at Crown Tribunal and the Starosta of Warka and one of its most notable inhabitants. Early in his youth, Casimir Pulaski studied at the local college of Theatines in Warsaw.

Sufjan Stevens ( /ˈsuːfjɑːn/ SOOF-yahn; born July 1, 1975) is an American singer-songwriter and musician born in Detroit, Michigan. Stevens first began releasing his music on Asthmatic Kitty, a label co-founded with his stepfather, beginning with the 1999 release, A Sun Came. He is best known for his 2005 album, Illinois, which hit number one in the Billboard Top Heatseekers chart, and for the song "Chicago".

Stevens has released albums of varying styles, from the electronica of Enjoy Your Rabbit and the lo-fi folk of Seven Swans to the symphonic instrumentation of Illinois and Christmas-themed Songs for Christmas. Stevens makes use of a variety of instruments, often playing many of them himself on the same recording, and writes music in various time signatures. Though he has repeatedly stated an intent to separate his beliefs from his music, Stevens also freely draws from the Bible and other spiritual traditions, incorporating mystical elements into his music often.

Stevens was born in Detroit and lived there until the age of nine, when his family moved to Petoskey, Michigan. In Petoskey he attended the Petoskey High School, the prestigious Interlochen Arts Academy and graduated from Harbor Light Christian School. He went on to attend Hope College in Holland, Michigan and earned a Master of Fine Arts from The New School in New York City.
