On October 9, 1824, the Rev. Patrick Davidson, pastor of the Presbyterian Church in Frederick, died. He began serving the church in 1809. He was also the principal of The Frederick Academy during part of his pastorate. On October 9, 1839, Winfield Scott Schley, the hero of an 1884 Arctic expedition and the 1898 Battle of Santiago, Cuba, was born at Richfield, the home that was built by Thomas Johnson just north of Frederick. On October 9, 1976, the Carroll Creek through downtown Frederick flooded again, bringing about a $65 million flood control project that was completed in 1991.
