Question:
Lehrer was born in 1928 to a Jewish family and grew up in Manhattan's Upper East Side. Although he was raised Jewish, Lehrer became an agnostic. He began studying classical piano at the age of seven, but was more interested in the popular music of the age. Eventually, his mother also sent him to a popular-music piano teacher.
Lehrer earned his Bachelor of Arts in mathematics (magna cum laude) from Harvard University in 1946. He received his MA degree the next year, and was inducted into Phi Beta Kappa. He taught classes at MIT, Harvard, Wellesley, and the University of California, Santa Cruz. He remained in Harvard's doctoral program for several years, taking time out for his musical career and to work as a researcher at the Los Alamos Scientific Laboratory. He was drafted into the U.S. Army from 1955 to 1957, working at the National Security Agency(NSA). (Lehrer has stated that he invented the Jell-O Shot during this time, as a means of circumventing liquor restrictions.) These experiences became fodder for songs, e.g., "The Wild West Is Where I Want to Be" and "It Makes a Fellow Proud to Be a Soldier". Interestingly, it was many years before Lehrer publicly revealed having been assigned to the NSA, since the mere 'fact-of' its existence was classified at the time: this left him in the interesting position of implicitly using nuclear weapons work as as cover story for something more sensitive. Despite holding a master's degree in an era when American conscripts often lacked a high school diploma, Lehrer served as an enlisted soldier, achieving the rank of Specialist Third Class (later retitled "Specialist-4" and currently "Specialist"), which he described as being a "corporal without portfolio." In 1960, Lehrer returned to full-time studies at Harvard, but in 1965 gave up on his mathematical dissertation about the subject of modes in statistics, after working on it intermittently for 15 years. From 1962, he taught in the political science department at the Massachusetts Institute of Technology (MIT). In 1972, he joined the faculty of the University of California, Santa Cruz, teaching an introductory course entitled "The Nature of Mathematics" to liberal arts majors--"Math for Tenors", according to Lehrer. He also taught a class in musical theater. He occasionally performed songs in his lectures, primarily those relating to the topic. In 2001, Lehrer taught his last mathematics class (on the topic of infinity) and retired from academia. He has remained in the area, and in 2003 said he still "hangs out" around the University of California, Santa Cruz.

Question:
Charles Elwood "Chuck" Yeager (; born February 13, 1923) is a retired United States Air Force general officer, flying ace and record-setting test pilot. In 1947, he became the first pilot confirmed to have exceeded the speed of sound in level flight. Yeager's career began in World War II as a private in the United States Army Air Forces.
In 1973, Yeager was inducted into the National Aviation Hall of Fame, arguably aviation's highest honor. In December 1975, the U.S. Congress awarded Yeager a silver medal "equivalent to a noncombat Medal of Honor ... for contributing immeasurably to aerospace science by risking his life in piloting the XS-1 research airplane faster than the speed of sound on October 14, 1947." President Gerald Ford presented the medal to Yeager in a ceremony at the White House on December 8, 1976. Yeager, who never attended college and was often modest about his background, is considered by many, including Flying Magazine, the California Hall of Fame, the State of West Virginia, National Aviation Hall of Fame, a few U.S. presidents, and the United States Army Air Force, to be one of the greatest pilots of all time. Despite his lack of higher education, he has been honored in his home state. Marshall University has named its highest academic scholarship, the Society of Yeager Scholars, in his honor. Yeager was also the chairman of Experimental Aircraft Association's Young Eagle Program from 1994-2004, and has been named the program's chairman emeritus. Yeager Airport in Charleston, West Virginia, is named in his honor. The Interstate 64/Interstate 77 bridge over the Kanawha River in Charleston is named in his honor. On October 19, 2006, the state of West Virginia also honored Yeager with a marker along Corridor G (part of U.S. 119) in his home Lincoln County, and also renamed part of the highway the Yeager Highway. Yeager is an honorary board member of the humanitarian organization Wings of Hope. On August 25, 2009, Governor Schwarzenegger and Maria Shriver announced that Yeager would be one of 13 California Hall of Fame inductees in The California Museum's yearlong exhibit. The induction ceremony was on December 1, 2009, in Sacramento, California. Flying Magazine ranked Yeager number 5 on its 2013 list of The 51 Heroes of Aviation; he is the highest-ranked living person on the list. The Civil Air Patrol, the volunteer auxiliary of the USAF, awards the Charles E. "Chuck" Yeager Award to its Senior Members as part of its Aerospace Education program. The General Chuck Yeager Cadet Squadron (SER-FL-237), associated with the Florida Wing, Civil Air Patrol, and based in Brandon, Florida, is also named in his honor.
