Question:
Musial was born in Donora, Pennsylvania, the fifth of the six children (four girls and two boys) of Lukasz and Mary (Lancos) Musial (, MOO-show). His mother was of Carpatho-Rusyn descent and his father was a Polish immigrant who chose the name Stanislaw Franciszek for his first son, though his father always referred to Musial using the Polish nickname Stasiu, pronounced "Stashu". Musial frequently played baseball with his brother Ed and other friends during his childhood, and considered Lefty Grove his favorite ballplayer. Musial also had the benefit of learning about baseball from his neighbor Joe Barbao, a former minor league pitcher.
Musial began the 1950s by posting a .350 batting average before participating in the 1950 All-Star Game, where in fan balloting he was the NL's number two choice. He had the longest hitting streak of his career during the 1950 season--a 30-game stretch that ended on July 27. With the Cardinals falling 14 games out of first place by September, manager Dyer used him at first base and all three outfield positions. New Cardinals manager Marty Marion led the team to a third-place finish in 1951, while Musial was named The Sporting News Major League Player of the Year. National media attention inadvertently turned to Musial a month before the 1952 season began, after Ty Cobb wrote an article regarding modern baseball players that was published in Life magazine. Cobb singled out Musial and Phil Rizzuto as the only players "who can be mentioned in the same breath with the oldtime greats". Cobb went on to refer to Musial as "a better player than Joe DiMaggio was in his prime." In response, Musial displayed his characteristic modesty, saying, "Cobb is baseball's greatest. I don't want to contradict him, but I can't say that I was ever as good as Joe DiMaggio." The only major league pitching appearance of Musial's career occurred as a publicity stunt during the last Cardinals home game of the 1952 season. Manager Eddie Stanky had a reluctant Musial pitch to Frank Baumholtz, the runner-up to Musial for the best batting average in the NL that season. With Baumholtz batting right-handed for the first time in his career, Musial's first pitch was hit so hard it ricocheted off the shin of third baseman Solly Hemus and into the left field corner. The play was ruled an error, and Musial was embarrassed enough by his complicity in the gimmick to avoid pitching again for the remainder of his career. The Cardinals franchise was up for sale in early 1953, and Musial and Schoendienst advised their friend and fellow duck-hunter Gussie Busch to consider buying the team. Busch used the resources of the Anheuser-Busch company to purchase the Cardinals, keeping Musial in St. Louis by averting the possibility of a move by the team to another city. The 1953 season marked Musial's 10th NL All-Star selection, and the 12th consecutive time he finished a major league season with a batting average above .300. Musial accomplished another historical feat on May 2, 1954, in a doubleheader in St. Louis against the New York Giants: he hit three home runs in the first contest, then added two more in the second to become the first major leaguer to hit five home runs in a doubleheader. In addition to his five home runs, he also hit a single in the first game, setting a new record of 21 total bases for a doubleheader. The only player besides Musial to hit five home runs in a doubleheader is Nate Colbert, who achieved the feat in 1972.

Question:
Kidder, one of five children, was born in Yellowknife, Northwest Territories, the daughter of Jocelyn Mary "Jill" (nee Wilson), a history teacher, and Kendall Kidder, an explosives expert and engineer. Kidder also spent time growing up in Labrador City, Newfoundland and Labrador. Her mother was from British Columbia, Canada, and her father was from New Mexico, United States. She is of Welsh and English descent.
In 1975, Kidder was cast in a lead role in The Great Waldo Pepper opposite Robert Redford, she also appeared in The Reincarnation of Peter Proud and 92 in the Shade (1975) with Peter Fonda, all of which established her as a commercially viable leading lady. Kidder famously married the director of 92 in the Shade, Thomas McGuane. She appeared on the March 9, 1975 edition of The American Sportsman, learning how to hang glide with her providing the narration and a remote microphone recording her reactions in flight; the segment concluded with Kidder doing solos soaring amid the Wyoming Rockies. After taking a break from acting after the birth of her daughter in 1976, Kidder sought to return to making films in the late 1970s. After doing a reading of Lois Lane for the 1978 superhero film Superman: The Movie, Kidder was flown to England by Richard Donner for screen-tests. Donner ultimately cast Kidder in the role, which would become her most iconic. Filming took over a year, and the film was released during Christmas 1978, to major commercial success. Kidder won a Saturn Award for best actress for her performance in the film. Kidder publicly disagreed with the decision of producers Alexander Salkind and Ilya Salkind to replace Richard Donner as director for Superman II (1980). It was reported that as a result, Kidder's role in Superman III (1983) consisted of less than five minutes of footage, though the producers have denied this in DVD commentaries. Her role in Superman IV: The Quest for Peace (1987) was more substantial. Kidder's performance as Kathy Lutz in the 1979 summer release of The Amityville Horror further cemented her status as one of Hollywood's leading ladies. Though it received mixed reviews from critics, The Amityville Horror was a major commercial success, grossing over $86 million in the United States. Janet Maslin of The New York Times, though giving the film a mixed review, said Kidder "stubbornly remains the bright-eyed life of the party [in the film]." In retrospect, Kidder called the film "a piece of shit." The same year, Kidder hosted an episode of the American sketch comedy TV show Saturday Night Live.
