Answer the question at the end by quoting:

De Benneville "Bert" Bell (February 25, 1895 - October 11, 1959) was the National Football League (NFL) commissioner from 1945 until his death in 1959. As commissioner, he introduced competitive parity into the NFL to improve the league's commercial viability and promote its popularity, and he helped make the NFL the most financially sound sports enterprise and preeminent sports attraction in the United States (US). He was posthumously inducted into the charter class of the Pro Football Hall of Fame. Bell played football at the University of Pennsylvania, where as quarterback, he led his team to an appearance in the 1917 Rose Bowl.
By early 1933, Bell's opinion on the NFL had changed, and he wanted to become an owner of a team based in Philadelphia. After being advised by the NFL that a prerequisite to a franchise being rendered in Philadelphia was that the Pennsylvania Blue Laws would have to be mollified, he was the force majeure in lobbying to getting the laws deprecated. He borrowed funds from Frances Upton, partnered with Wray, and he procured the rights to a franchise in Philadelphia which he christened as the Philadelphia Eagles.  After the inaugural 1933 Philadelphia Eagles season, Bell married Upton at St. Madeleine Sophie Roman Catholic Church in Philadelphia. Days later, his suggestion to bestow the winner of the NFL championship game with the Ed Thorp Memorial Trophy was affirmed. In 1934, the Eagles finished with a 4-7 record, The Eagles' inability to seriously challenge other teams made it difficult to sell tickets, and his failure to sign a talented college prospect led him to adduce that the only way to bring stability to the league was to institute a draft to ensure the weakest teams had an advantage in signing the preeminent players. In 1935, his proposal for a draft was accepted, and in February 1936, the first draft kicked off, at which he acted as Master of Ceremonies. Later that month, his first child, Bert Jr., was born.  In the Eagles' first three years, the partners exhausted $85,000 (presently, $1,499,017), and at a public auction, Bell became sole owner of the Eagles with a bid of $4,500 (presently, $79,360). Austerity measures forced him to supplant Wray as head coach of the Eagles, wherein Bell led the Eagles to a 1-11 finish, their worst record ever. In December, an application for a franchise in Los Angeles was obstructed by Bell and Pittsburgh Steelers owner Rooney as they deemed it too far of a distance to travel for games. During the Eagles' 2-8-1 1937 season, his second child, John "Upton", was born. In the Eagles' first profitable season, 1938, they posted a 5-6 record. The Eagles finished 1-9-1 in 1939 and 1-10 in 1940.

So was he the first owner of the Eagles?

Some context: Ernst Theodor Amadeus Hoffmann (commonly abbreviated as E. T. A. Hoffmann; born Ernst Theodor Wilhelm Hoffmann; 24 January 1776 - 25 June 1822) was a Prussian Romantic author of fantasy and Gothic horror, a jurist, composer, music critic, draftsman and caricaturist. His stories form the basis of Jacques Offenbach's famous opera The Tales of Hoffmann, in which Hoffmann appears (heavily fictionalized) as the hero. He is also the author of the novella The Nutcracker and the Mouse King, on which Pyotr Ilyich Tchaikovsky's ballet The Nutcracker is based. The ballet Coppelia is based on two other stories that Hoffmann wrote, while Schumann's Kreisleriana is based on Hoffmann's character Johannes Kreisler.
Hoffmann assimilated well with Polish society; the years spent in Prussian Poland he recognized as the happiest of his life. In Warsaw he found the same atmosphere he had enjoyed in Berlin, renewing his friendship with Zacharias Werner, and meeting his future biographer, a neighbour and fellow jurist called Julius Eduard Itzig (who changed his name to Hitzig after his baptism). Itzig had been a member of the Berlin literary group called the Nordstern, and he gave Hoffmann the works of Novalis, Ludwig Tieck, Achim von Arnim, Clemens Brentano, Gotthilf Heinrich von Schubert, Carlo Gozzi, and Calderon. These relatively late introductions marked his work profoundly.  He moved in the circles of August Wilhelm Schlegel, Adelbert von Chamisso, Friedrich de la Motte Fouque, Rahel Levin, and David Ferdinand Koreff.  His fortunate position was not to last: on 28 November 1806, during the War of the Fourth Coalition, Napoleon Bonaparte's troops captured Warsaw, and the Prussian bureaucrats lost their jobs. They divided the contents of the treasury between them and fled. In January 1807 his wife and two-year-old daughter Cacilia returned to Posen, while he pondered whether to move to Vienna or go back to Berlin. A delay of six months was caused by severe illness. Eventually the French authorities demanded that all former officials swear allegiance or leave the country. As they refused to grant him a passport to Vienna, he was forced to return to Berlin. He visited his family in Posen before arriving in Berlin on 18 June 1807, hoping to further his career there as an artist and writer.

IN: Arijit Singh is an Indian musician, singer, composer, music producer, recordist and music programmer. He sings predominantly in Hindi and Bengali, but has also lent his voice to various other Indian languages. Singh is regarded as one of the most versatile and successful singers in the History of Indian Music and Hindi Cinema. At the start of his singing career, he received nominations for the Upcoming Male Vocalist of the Year award at the 2013 Mirchi Music Awards for renditions of "Phir Le Aya Dil" and "Duaa", winning the award for the latter.

Singh has played a great role in the Bollywood singing career of one of his contemporaries today Ash King. Regarding his help King told the Times of India, "When I met Arijit in London through a mutual friend, he wasn't a star singer yet. I knew he'd be big someday. When I came back (to Kolkata) in 2010, Arijit invited me to Mumbai and recommended me to Pritam for the song 'I Love You' and 'Te Amo'. He has been a great motivating force."  Singh said in an interview that he would love to serve people through his NGO named "Let There Be Light" which works for the Below Poverty Line (BPL) community. His NGO aims to include activities like bloodbank camp (with proof and records and photographs of all the blood being delivered properly), distribution of clothes, books, stationery, etc. to Below Poverty Line children on a huge scale and seasonal human ground activities.  In an interview, he spoke about his desire to work for people. "I try and help people in whichever way I can. I owned an NGO long time ago which is now turned into something which helps the people in whichever way they can. For example, we collected a lot of things for victims of the Nepal earthquake. The biggest problem is that we are not ready for anything bad that happens, be it during disasters or helping people post one. For example, the first earthquake in Nepal happened on 25 April and it took me a while to collect something as basic as matchboxes, candles and so on. People basically are not ready to help others. I firmly feel that we over here need a lot of awareness when it comes to population and at times I even feel bad for the Government."
