David Monroe Shoup (30 December 1904 - 13 January 1983) was a decorated general of the United States Marine Corps who was awarded the Medal of Honor in World War II, became the 22nd Commandant of the Marine Corps, and, after retiring, became one of the most prominent critics of the Vietnam War. Born in Indiana to an impoverished family, Shoup joined the military for financial reasons. Rising through the ranks in the interwar era, he was twice deployed to China during the Chinese Civil War. He served in Iceland at the beginning of U.S. involvement in World War II, and as a staff officer during the Pacific War.
David Monroe Shoup was born on 30 December 1904 in Battle Ground, Indiana. His family lived on a farm in Ash Grove, but moved to Covington to live on a new farm in 1916. At age 12 he was enrolled in Covington High School, a competitive high school with an advanced curriculum. Shoup was an excellent student, maintaining high marks in French, English, physics, and history. Additionally, he was involved in several extracurricular activities, including basketball, and was class president in his senior year. He graduated in 1921. He later affectionately referred to his impoverished upbringing as that of an "Indiana plowboy." Regarded by friends as very sociable, he met Zola De Haven in his freshman year and later said he had been instantly attracted to her. They were both very competitive in academics and athletics, and the two dated throughout high school; they were married in 1931. After high school, Shoup attended DePauw University where he was one of 100 awarded the Edward Rector Scholarship, giving him full tuition. Majoring in mathematics, he joined the Delta Upsilon fraternity and maintained high marks, narrowly failing the selection criteria for Phi Beta Kappa Society. He was on the track and field and rifle teams, and also competed in the wrestling and football teams. He won the Indiana and Kentucky Amateur Athletic Union marathon in 1925. He waited tables, washed dishes and worked in a cement factory to help pay his expenses. Lack of funds compelled him to take a year off after his junior year to teach school, and his expenses were further strained when he contracted a severe case of pneumonia and incurred hospital bills. He opted to enroll in the Reserve Officers Training Corps (ROTC) to offset his living expenses, and later recalled that this was the only reason he joined the military. He graduated from DePauw in 1926. From an early age, Shoup was molded by the progressive ideas of Indiana politicians, sympathizing with rural progressives fighting against the interests of big businesses. He developed an anti-imperialist attitude, and his skepticism about American foreign policy, influenced by his small-town background, made him an outspoken opponent of the unnecessary use of military force. He felt the use of troops for economic or imperialist consideration was wrong, a viewpoint he would carry for his entire career.

What did he major in?

Majoring in mathematics,

The Bee Gees were a pop music group formed in 1958. Their lineup consisted of brothers Barry, Robin, and Maurice Gibb. The trio were successful for most of their decades of recording music, but they had two distinct periods of exceptional success: as a popular music act in the late 1960s and early 1970s, and as prominent performers of the disco music era in the mid-to-late 1970s. The group sang recognisable three-part tight harmonies; Robin's clear vibrato lead vocals were a hallmark of their earlier hits, while Barry's R&B falsetto became their signature sound during the mid-to-late 1970s and 1980s.
At Eric Clapton's suggestion, the brothers moved to Miami, Florida, early in 1975 to record. After starting off with ballads, they eventually heeded the urging of Mardin and Stigwood, and crafted more dance-oriented disco songs, including their second US No. 1, "Jive Talkin'", along with US No. 7 "Nights on Broadway". The band liked the resulting new sound. This time the public agreed by sending the LP Main Course up the charts. This album included the first Bee Gees songs wherein Barry used falsetto, something that would later become a trademark of the band. This was also the first Bee Gees album to have two US top-10 singles since 1968's Idea. Main Course also became their first charting R&B album. On the Bee Gees' appearance on The Midnight Special in 1975, to promote Main Course, they sang "To Love Somebody" with Helen Reddy. Around the same time, the Bee Gees recorded three Beatles covers--"Golden Slumbers/Carry That Weight", "She Came in Through the Bathroom Window" with Barry providing lead vocals, and "Sun King" with Maurice providing lead vocals, for the unsuccessful musical/documentary All This and World War II. The next album, Children of the World released in September 1976, was drenched in Barry's new-found falsetto and Weaver's synthesizer disco licks. Mardin was unavailable to produce, so the Bee Gees enlisted Albhy Galuten and Karl Richardson, who had worked with Mardin during the Main Course sessions. This production team would carry the Bee Gees through the rest of the 1970s. The first single from the album was "You Should Be Dancing" (which features percussion work by musician Stephen Stills). The song pushed the Bee Gees to a level of stardom they had not previously achieved in the US, though their new R&B/disco sound was not as popular with some die hard fans. The pop ballad "Love So Right" reached No. 3 in the US, and "Boogie Child" reached US No. 12 in January 1977. The album peaked at No. 8 in the US. A compilation Bee Gees Gold was released in November, containing the group's hits from 1967 to 1972.
