Conn is a surname and a masculine given name meaning "chief" in Irish. As a given name it is also used as a short form of Connor.

Justin Williams (born October 4, 1981) is a Canadian professional ice hockey right winger who currently plays for the Los Angeles Kings of the National Hockey League (NHL). He has also played for the Philadelphia Flyers and the Carolina Hurricanes.

Justin Williams grew up in Cobourg, Ontario and played minor hockey in nearby Port Hope of the OMHA before gaining a reputation as a skilled playmaker with the Cobourg Cougars Jr.A. (OHA) in 1997-98.

Williams was drafted in the 6th round (125th overall) by the Plymouth Whalers in the 1998 OHL Priority Selection. Williams was signed as a 16-year old by the Whalers and split time between the OHL club and their affiliate Compuware Jr.A. club (NAHL) in the 1998-99 season. He finished his Juniors hockey with two seasons played for the Plymouth Whalers of the Ontario Hockey League.

In four seasons played with the Philadelphia Flyers, Williams struggled to live up to expectations as he tried to adapt to the varying systems of three separate coaches, Craig Ramsay (2000), Bill Barber (2000–02), and Ken Hitchcock (2002–06). Williams was also frequently injured, perhaps hampering his development. He broke his left hand in his rookie season (hit by David Tanabe, Carolina Hurricanes), and had various sprains and strains in his sophomore year. Williams suffered a left knee injury on January 18, 2003, when he was hit low by Tampa Bay's Brad Lukowich. The hit tore Williams's ACL and MCL, and on January 23, 2003, he had surgery to repair the ligaments. Originally projected to miss 4–8 months recovering from the injury, Williams made it back into Philadelphia's lineup in just three months.

Constantine Falkland Cary Smythe MC (February 1, 1895 – November 18, 1980) was a Canadian businessman, soldier and sportsman in ice hockey and horse racing. He is best known as the principal owner of the Toronto Maple Leafs of the National Hockey League (NHL) from 1927 to 1961 and as the builder of Maple Leaf Gardens. As owner of the Leafs during numerous championship years, his name appears on the Stanley Cup eight times: 1932, 1942, 1945, 1947, 1948, 1949, 1951, 1962.

Smythe is also known for having served in both World Wars, organizing his own artillery battery in the Second World War. The horses of Smythe's racing stable won the Queen's Plate twice among 145 stakes races wins during his lifetime. Smythe started and ran a successful sand and gravel business. He was a big supporter of the Ontario Society for Crippled Children and the Variety Club and founded the Conn Smythe Foundation philanthropic organization.

Conn Smythe was born on February 1, 1895, in Toronto to Albert Smythe, an Irish Protestant from County Antrim who immigrated to Canada in 1889, and Mary Adelaide Constantine, an English woman. Mary and Albert were married in the 1880s while immigrating to Canada. Albert and Mary had a rocky marriage and did not live together for more than a few months at a time. Mary, who was known as Polly, was remembered by Conn as pretty, a drinker and troublemaker, while Albert was quiet, a vegetarian and a devoted member of Madame Blavatsky's Theosophical movement. Albert Smythe was a charter member of the Theosophical Society of Canada in 1891, and edited its newsletter until the final years of his life.

Joseph Louis Barrow (May 13, 1914 – April 12, 1981), better known as Joe Louis, was an American professional boxer and the World Heavyweight Champion from 1937 to 1949. He is considered to be one of the greatest heavyweights of all time. Nicknamed the Brown Bomber, Louis helped elevate boxing from a nadir in popularity in the post-Jack Dempsey era by establishing a reputation as an honest, hardworking fighter at a time when the sport was dominated by gambling interests. Louis' championship reign lasted 140 consecutive months, during which he participated in 27 championship fights, 26 championship fights during his reign; the 27th, against Ezzard Charles, was a challenge to Charles' Heavyweight title and so is not included in Louis' reign. All in all, Joe was victorious in 25 successful title defenses, a record for the heavyweight division. In 2005, Louis was ranked as the #1 heavyweight of all-time by the International Boxing Research Organization, and was ranked #1 on The Ring's list of the 100 Greatest Punchers of All-Time.

William David Conn (October 8, 1917–May 29, 1993), better known as Billy Conn, was an American professional boxer and Light Heavyweight Champion famed for his fights with Joe Louis. He had a professional boxing record of 63 wins, 11 losses and 1 draw, with 14 wins by knockout. His nickname, throughout most of his career, was "The Pittsburgh Kid."

Conn debuted as a professional boxer on June 28, 1934, losing to Dick Woodward (Frank Colwin Woodward, known as Woody later in his life in California) by a decision in four rounds. His first win came almost a month later, on July 20, against Johnny Lewis, via a knockout in round three.

Conn built a record of 47 wins, 9 losses and 1 draw (tie), with 7 knockout wins, before challenging for the World Light Heavyweight title. Along the way, he beat former or future world champions Fritzie Zivic, Solly Krieger and Fred Apostoli, as well as Teddy Yarosz and Young Corbett III.

On July 13, 1939, he met World Light Heavyweight Champion Melio Bettina in New York, outpointing him in 15 rounds and winning the World LightHeavyweight Championship. Conn defended his title against Bettina and twice against another World Light Heavyweight Champion, Gus Lesnevich, each of those three bouts resulting in 15 round decision wins for Conn. Conn also beat former World Middleweight Champion Al McCoy and heavyweights Bob Pastor, Lee Savold, Gunnar Barlund and Buddy Knox in non-title bouts during his run as World Light Heavyweight Champion.
