Seattle Slew (February 15, 1974 - May 7, 2002) was an American Thoroughbred race horse who won the Triple Crown in 1977--the tenth of twelve horses to accomplish the feat. He is the only horse to have won the Triple Crown while having been undefeated in any race previous. Honored as the 1977 Horse of the Year, he was also a champion at age two, three and four. In the Blood-Horse magazine List of the Top 100 U.S. Racehorses of the 20th Century Seattle Slew was ranked ninth.
Seattle Slew stood at stud at Spendthrift Farm in Lexington for seven years, before moving to Three Chimneys Farm in Midway in 1985. He was the leading sire of 1984, when his son Swale (who died later that year) won the Kentucky Derby and Belmont Stakes. His other progeny include the talented, ill-fated 1982 champion two-year-old filly, Landaluce, Slew o' Gold (winner of the 1983 Eclipse Award for Outstanding Three-Year-Old Male Horse and the 1984 Eclipse Award for Outstanding Older Male Horse), 1992 Horse of the Year A.P. Indy and the 2000 champion three-year-old filly Surfside. He is part of a unique three generation sequence of Belmont Stakes Winners: Seattle Slew (1977) - A.P. Indy (1992) - Rags to Riches (2004).  The primary conduit for Seattle Slew's continuation of his male line has been through A.P. Indy. A.P. Indy has done well at stud in Kentucky, siring (among others) the 2003 Horse of the Year, Mineshaft. One of Seattle Slew's most successful grandsons is the California champion Lava Man (sired by Slew City Slew). In 2006, Lava Man became the first horse to win the Santa Anita Handicap, Hollywood Gold Cup and Pacific Classic Stakes in the same year. Seattle Slew was also a leading broodmare sire, his daughters producing (among others) Cigar (leading North American money-earner of his day). Races in honor of his dam, My Charmer, include the My Charmer Handicap held at Florida's Calder Race Course annually and the My Charmer Stakes held at Kentucky's Turfway Park.  Rags to Riches, a granddaughter, won the 2007 Belmont Stakes - the third filly to win the race, after Ruthless in 1867 and Tanya in 1905. The victory earned jockey John Velazquez and trainer Todd Pletcher their first wins in any Triple Crown race. Rags To Riches was the 22nd filly to run in the Belmont. In 2002, ESPN telecast a "SportsCentury" on Seattle Slew.  In 2014, Seattle Slew's great-great grandson, California Chrome, won the Kentucky Derby  and the Preakness. California Chrome was the second Kentucky Derby winner in a row who was a sire-line descendant of Seattle Slew, following Orb in 2013. California Chrome's bid for the Triple Crown was defeated by another great-grandson of Seattle Slew, Tonalist, by leading sire Tapit. Tapit also sired the winners of the 2016 and 2017 Belmont Stakes, Creator and Tapwrit respectively.  25 years to the day after he won the Kentucky Derby, Seattle Slew died in his sleep at age 28. He was buried whole, the highest honor for a winning race horse, in the courtyard at Hill 'N' Dale Farm near Lexington, Kentucky, with his favorite blanket and a bag of peppermints which he liked to eat. Three Chimneys Farm erected a statue of Seattle Slew near the stallion barn in his honor. Since fellow Triple Crown winner and rival Affirmed had died the year before, he was the sole living Triple Crown winner. At the horse's death, there were no living Triple Crown winners for the first time since Sir Barton won the first Triple Crown in 1919. This phenomenon continued until American Pharoah's Triple Crown in 2015.

When did he retire?

Answer the question at the end by quoting:

James Byron Dean was born on February 8, 1931, at the Seven Gables apartment on the corner of 4th Street and McClure Street in Marion, Indiana, the only child of Winton Dean and Mildred Marie Wilson. He was primarily of English descent, with smaller amounts of German, Irish, Scottish, and Welsh ancestry. Six years after his father had left farming to become a dental technician, Dean and his family moved to Santa Monica, California. He was enrolled at Brentwood Public School in the Brentwood neighborhood of Los Angeles, California, but transferred soon afterward to the McKinley Elementary School.
Dean's first television appearance was in a Pepsi Cola commercial. He quit college to act full-time and was cast in his first speaking part, as John the Beloved Disciple, in Hill Number One, an Easter television special dramatizing the Resurrection of Jesus. Dean worked at the widely filmed Iverson Movie Ranch in the Chatsworth area of Los Angeles during production of the program, for which a replica of the tomb of Jesus was built on location at the ranch. Dean subsequently obtained three walk-on roles in movies: as a soldier in Fixed Bayonets!, a boxing cornerman in Sailor Beware, and a youth in Has Anybody Seen My Gal?  While struggling to get jobs in Hollywood, Dean also worked as a parking lot attendant at CBS Studios, during which time he met Rogers Brackett, a radio director for an advertising agency, who offered him professional help and guidance in his chosen career, as well as a place to stay.  In July 1951, Dean appeared on Alias Jane Doe, which was produced by Brackett. In October 1951, following the encouragement of actor James Whitmore and the advice of his mentor Rogers Brackett, Dean moved to New York City. There, he worked as a stunt tester for the game show Beat the Clock, but was subsequently fired for allegedly performing the tasks too quickly. He also appeared in episodes of several CBS television series The Web, Studio One, and Lux Video Theatre, before gaining admission to the Actors Studio to study method acting under Lee Strasberg.  Proud of this accomplishment, Dean referred to the Actors Studio in a 1952 letter to his family as "the greatest school of the theater. It houses great people like Marlon Brando, Julie Harris, Arthur Kennedy, Mildred Dunnock, Eli Wallach... Very few get into it ... It is the best thing that can happen to an actor. I am one of the youngest to belong." There, he was classmates and close friends with Carroll Baker, alongside whom he would eventually star in Giant (1956).  Dean's career picked up and he performed in further episodes of such early 1950s television shows as Kraft Television Theatre, Robert Montgomery Presents, The United States Steel Hour, Danger, and General Electric Theater. One early role, for the CBS series Omnibus in the episode "Glory in the Flower", saw Dean portraying the type of disaffected youth he would later portray in Rebel Without a Cause. This summer 1953 program was also notable for featuring the song "Crazy Man, Crazy", one of the first dramatic TV programs to feature rock and roll. Positive reviews for Dean's 1954 theatrical role as Bachir, a pandering North African houseboy, in an adaptation of Andre Gide's book The Immoralist, led to calls from Hollywood.

did he work in any movies early in his career?
Dean subsequently obtained three walk-on roles in movies: as a soldier in Fixed Bayonets!, a boxing cornerman in Sailor Beware, and a youth in Has Anybody Seen My Gal?
