Question:
William Miller Edwards (June 21, 1905 - June 12, 1987) was an American football player and coach. He served as the head football coach at Western Reserve University, Vanderbilt University and Wittenberg University in a career lasting more than 30 years, compiling a win-loss-tie record of 168-45-8. Edwards also coached the Detroit Lions of the National Football League (NFL) from 1941 to 1942, tallying a 4-9-1 record, and served as an assistant coach for the NFL's Cleveland Browns in the late 1940s. Raised near Massillon, Ohio, Edwards was the son of an immigrant from Wales who worked in the area's coal mines.
Edwards resigned from coaching in 1969, when he was 63 years old, although he continued to work at Wittenberg as the school's athletic director. Dave Maurer, his long-time assistant, took over as the school's coach. By the end of his career, Edwards's 168-45-8 overall college record gave him the second-best winning percentage in the country among active coaches with at least 100 wins. Edwards was given a commendation by President Richard Nixon for his achievements as a coach and won a Football Writers Association of America award for contributions to the game. "His retirement is Wittenberg's loss, but more than that, it is college football's loss," University of Alabama coach Bear Bryant said at the time. Edwards retired in February 1973 after 39 years as a coach and administrator and said he would concentrate on hunting and fishing. He was inducted into the Ohio Football Coaches Association Hall of Fame in 1979, Wittenberg's Athletics Hall of Honor in 1985 and into the College Football Hall of Fame in 1986. He was also inducted into the Western Reserve Hall of Fame and the Vanderbilt Hall of Fame in 1986. Edwards died in 1987. He and his wife Dorothy had three children. The tough but compassionate approach to coaching Edwards espoused influenced many men who worked under him, including Maurer, who led Wittenberg to a 129-23-3 record between 1969 and 1983. Wittenberg's football stadium is named Edwards-Maurer Field in honor of both head coaches. The winner of the Wittenberg-Case Western Reserve football game receives the Bill Edwards Trophy. Edwards was also close with Steve Belichick, who played for him at Western Reserve and for the Detroit Lions and later served as an assistant under him at Vanderbilt and North Carolina. Belichick's son Bill was named after Edwards, who was also Bill's godfather. Bill Belichick later became an assistant coach in the NFL and is the head coach of the New England Patriots as of 2018. At what is now known as Case Western Reserve University, the football stadium, DiSanto Field, hosts its distinguished guests inside the Coach Bill Edwards President's Suite.

Question:
James Buchanan Jr. was born in a log cabin in Cove Gap, Pennsylvania (now Buchanan's Birthplace State Park), in Franklin County, on April 23, 1791, to James Buchanan, Sr. (1761-1821), a businessman, merchant, and farmer, and Elizabeth Speer, an educated woman (1767-1833). His parents were both of Ulster Scottish descent, the father having emigrated from Milford, County Donegal, Ireland, in 1783. One of eleven siblings, Buchanan was the oldest child in the family to survive infancy.
The Civil War erupted within two months of Buchanan's retirement. He supported the United States, writing to former colleagues that "the assault upon Sumter was the commencement of war by the Confederate states, and no alternative was left but to prosecute it with vigor on our part". He also wrote a letter to his fellow Pennsylvania Democrats, urging them to "join the many thousands of brave & patriotic volunteers who are already in the field". Buchanan spent most of his remaining years defending himself from public blame for the Civil War, which was even referred to by some as "Buchanan's War". He began receiving angry and threatening letters daily, and stores displayed Buchanan's likeness with the eyes inked red, a noose drawn around his neck and the word "TRAITOR" written across his forehead. The Senate proposed a resolution of condemnation which ultimately failed, and newspapers accused him of colluding with the Confederacy. His former cabinet members, five of whom had been given jobs in the Lincoln administration, refused to defend Buchanan publicly. Initially so disturbed by the attacks that he fell ill and depressed, Buchanan finally began defending himself in October 1862, in an exchange of letters between himself and Winfield Scott that was published in the National Intelligencer newspaper. He soon began writing his fullest public defense, in the form of his memoir Mr. Buchanan's Administration on the Eve of Rebellion, which was published in 1866. Buchanan caught a cold in May 1868, which quickly worsened due to his advanced age. He died on June 1, 1868, from respiratory failure at the age of 77 at his home at Wheatland and was interred in Woodward Hill Cemetery in Lancaster.
