Problem: Background: 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.
Context: At the 1904 Louisiana Purchase Exposition, Valdemar Poulsen had presented a paper on an arc transmitter, which unlike the discontinuous pulses produced by spark transmitters, created steady "continuous wave" signals that could be used for amplitude modulated (AM) audio transmissions. Although Poulsen had patented his invention, de Forest claimed to have come up with a variation that allowed him to avoid infringing on Poulsen's work. Using his "sparkless" arc transmitter, de Forest first transmitted audio across a lab room on December 31, 1906, and by February was making experimental transmissions, including music produced by Thaddeus Cahill's telharmonium, that were heard throughout the city. On July 18, 1907, de Forest made the first ship-to-shore transmissions by radiotelephone -- race reports for the Annual Inter-Lakes Yachting Association (I-LYA) Regatta held on Lake Erie -- which were sent from the steam yacht Thelma to his assistant, Frank E. Butler, located in the Fox's Dock Pavilion on South Bass Island. De Forest also interested the U.S. Navy in his radiotelephone, which placed a rush order to have 26 arc sets installed for its Great White Fleet around-the-world voyage that began in late 1907. However, at the conclusion of the circumnavigation the sets were declared to be too unreliable to meet the Navy's needs and removed. The company set up a network of radiotelephone stations along the Atlantic coast and the Great Lakes, for coastal ship navigation. However, the installations proved unprofitable, and by 1911 the parent company and its subsidiaries were on the brink of bankruptcy.

Context: In the following months, Jericho became a major force in The Invasion storyline in which WCW and ECW joined forces to overtake the WWF. Jericho remained on the side of the WWF despite previously competing in WCW and ECW. However, Jericho began slow turning into a villain by showing jealousy toward fellow WWF member The Rock. They faced each other in a match at No Mercy for the WCW Championship after Jericho defeated Rob Van Dam in a number one contenders match. Jericho won the WCW Championship when he pinned The Rock after debuting a new finisher, the Breakdown, onto a steel chair, winning his first world title in the process. One night later, the two put their differences aside and won the WWF Tag Team title from the Dudley Boyz. After they lost the title to Test and Booker T, they continued their feud. On the November 5 episode of Raw, The Rock defeated Jericho to regain the WCW Championship. Following the match, Jericho attacked The Rock with a steel chair. At Survivor Series, Jericho solidified his heel turn by almost costing The Rock, and the WWF, victory in their elimination matchup by attacking The Rock again. At Vengeance, Jericho defeated both The Rock for the WCW Championship (unbranded and only referred to as the World Championship following Survivor Series) and Stone Cold Steve Austin for his first WWF Championship on the same night to become the first wrestler to hold both championships at the same time, which made him the first-ever Undisputed WWF Champion, as well as the fourth Grand Slam winner under the original format. He retained the title at Royal Rumble against The Rock and at No Way Out against Austin. Jericho later lost the title to Triple H in the main event of WrestleMania X8. After his title loss, Jericho became a member of the SmackDown! roster and continued his feud with Triple H. The rivalry culminated at Judgment Day when Triple H defeated Jericho in a Hell in a Cell match.
