Some context: Yelberton Abraham Tittle Jr. (October 24, 1926 - October 8, 2017), better known as Y. A. Tittle, was a professional American football quarterback. He played in the National Football League (NFL) for the San Francisco 49ers, New York Giants, and Baltimore Colts, after spending two seasons with the Colts in the All-America Football Conference (AAFC). Known for his competitiveness, leadership, and striking profile, Tittle was the centerpiece of several prolific offenses throughout his seventeen-year professional career from 1948 to 1964. Tittle played college football for Louisiana State University, where he was a two-time All-Southeastern Conference (SEC) quarterback for the LSU Tigers football team.
At the time of his retirement, Tittle held the following NFL records:  Tittle was the fourth player to throw seven touchdown passes in a game, when he did so in 1962 against the Redskins. He followed Sid Luckman (1943), Adrian Burk (1954), and George Blanda (1961). The feat has since been equaled by four more players: Joe Kapp (1969), Peyton Manning (2013), Nick Foles (2013), and Drew Brees (2015). Tittle, Manning and Foles did it without an interception. His 36 touchdown passes in 1963 set a record which stood for over two decades until it was surpassed by Dan Marino in 1984; as of 2016 it remains a Giants franchise record.  Despite record statistics and three straight championship game appearances, Tittle was never able to deliver a title to his team. His record as a starter in postseason games was 0-4. He threw four touchdown passes against 14 interceptions and had a passer rating of 33.8 in his postseason career, far below his regular season passer rating of 74.3. Seth Wickersham, writing for ESPN The Magazine in 2014, noted the dichotomy in the 1960s between two of New York's major sports franchises: "... Gifford, Huff and Tittle, a team of Hall of Famers known for losing championships as their peers on the Yankees--with whom they shared a stadium, a city, and many rounds of drinks--became renowned for winning them." The Giants struggled after Tittle's retirement, posting only two winning seasons from 1964 to 1980.  He made seven Pro Bowls, four first-team All-Pro teams, and four times was named the NFL's Most Valuable Player or Player of the Year: in 1957 and 1962 by the UPI; in 1961 by the NEA; and in 1963 by the AP and NEA. In a sports column in 1963, George Strickler for the Chicago Tribune remarked Tittle had "broken records that at one time appeared unassailable and he has been the hero of more second half rallies than Napoleon and the Harlem Globetrotters." He was featured on four Sports Illustrated covers: three during his playing career and one shortly after retirement. His first was with the 49ers in 1954. With the Giants, he graced covers in November 1961, and he was on the season preview issue for 1964; a two-page fold-out photo from the 1963 title game. Tittle was on a fourth cover in August 1965.  The trade of Tittle for Lou Cordileone is seen as one of the worst trades in 49ers history; it is considered one of the best trades in Giants franchise history. Cordileone played just one season in San Francisco.

Some context: Lee de Forest was born in 1873 in Council Bluffs, Iowa, the son of Anna Margaret (nee Robbins) and Henry Swift DeForest. He was a direct descendant of Jesse de Forest, the leader of a group of Walloon Huguenots who fled Europe in the 17th Century due to religious persecution. De Forest's father was a Congregational Church minister who hoped his son would also become a pastor. In 1879 the elder de Forest became president of the American Missionary Association's Talladega College in Talladega, Alabama, a school "open to all of either sex, without regard to sect, race, or color", and which educated primarily African-Americans.
One of de Forest's areas of research at Federal Telegraph was improving the reception of signals, and he came up with the idea of strengthening the audio frequency output from a grid Audion by feeding it into a second tube for additional amplification. He called this a "cascade amplifier", which eventually consisted of chaining together up to three Audions.  At this time the American Telephone and Telegraph Company was researching ways to amplify telephone signals to provide better long-distance service, and it was recognized that de Forest's device had potential as a telephone line repeater. In mid-1912 an associate, John Stone Stone, contacted AT&T to arrange for de Forest to demonstrate his invention. It was found that de Forest's "gassy" version of the Audion could not handle even the relatively low voltages used by telephone lines. (Due to the way he constructed the tubes, de Forest's Audions would cease to operate with too high a vacuum.) However, careful research by Dr. Harold D. Arnold and his team at AT&T's Western Electric subsidiary determined that by improving the tube's design, it could be more fully evacuated, and the high vacuum allowed it to successfully operate at telephone line voltages. With these changes the Audion evolved into a modern electron-discharge vacuum tube, using electron flows rather than ions. (Dr. Irving Langmuir at the General Electric Corporation made similar findings, and both he and Arnold attempted to patent the "high vacuum" construction, but the U.S. Supreme Court ruled in 1931 that this modification could not be patented).  After a delay of ten months, in July 1913 AT&T, through a third party who disguised his link to the telephone company, purchased the wire rights to seven Audion patents for $50,000. De Forest had hoped for a higher payment, but was again in bad financial shape and was unable to bargain for more. In 1915, AT&T used the innovation to conduct the first transcontinental telephone calls, in conjunction with the Panama-Pacific International Exposition at San Francisco.
