Problem: Background: William Abb Cannon (born August 2, 1937) is a former American football running back and tight end who played professionally in the American Football League (AFL) and National Football League (NFL). He attended Louisiana State University (LSU), where he played college football as a halfback and return specialist for the LSU Tigers. At LSU, Cannon was twice unanimously named an All-American, helped the 1958 LSU team win a national championship, and received the Heisman Trophy as the nation's most outstanding college player in 1959. His punt return against Ole Miss on Halloween night in 1959 is considered by fans and sportswriters to be one of the most famous plays in LSU sports history.
Context: Cannon married his high school sweetheart, Dot Dupuy, while they were both freshmen at LSU. They have five children together. His son Billy Cannon Jr. played as a linebacker for Texas A&M and was selected in the first round of the 1984 NFL Draft by the Dallas Cowboys. Cannon Sr. graduated from LSU in 1959 and completed post-graduate studies at the University of Tennessee during the Oilers' off-season. There, he earned a D.D.S.; later, he earned additional degrees in orthodontia from Loyola University Chicago. After retiring from football, he returned to Baton Rouge and started his own dental practice. Despite a successful practice, by 1983 he was in financial difficulties from bad real estate investments and gambling debts. Becoming involved in a counterfeiting scheme, he printed $6 million in U.S. 100-dollar bills, some of which he stored in ice chests buried in the back yard of a house he owned and rented out. Charged along with five others, he served two-and-a-half years of a five-year sentence at the Federal Correctional Institution, Texarkana. Upon his release in 1986, he regained his dentistry license but struggled to rebuild his practice. In 1995, he was hired as a dentist at the Louisiana State Penitentiary, initially as a contractor. At the time, the dental clinic in the prison was in chaos; many dentists refused to work there and inmates were often unable to make appointments. Cannon reorganized the dental program with great success and was soon hired as a full-time employee. Warden Burl Cain, impressed with Cannon's work with the dental program, put him in charge of the prison's entire medical system. Cannon remains the resident dentist at the penitentiary, where inmates typically call him "Legend". Cannon resides in St. Francisville, Louisiana with his wife. In February 2013, Cannon suffered a stroke and was hospitalized in Baton Rouge. He was released two days later, returned to work the following Monday, and made a full recovery.
Question: Did Cannon have any children?
Answer: They have five children together.

Problem: Background: Robert Walser (15 April 1878 - 25 December 1956) was a German-speaking Swiss writer. Walser is understood to be the missing link between Kleist and Kafka. "Indeed," writes Susan Sontag, "At the time [of Walser's writing], it was more likely to be Kafka [who was understood by posterity] through the prism of Walser. Robert Musil, another admirer among Walser's contemporaries, when he first read Kafka pronounced [Kafka's work] as, 'a peculiar case of the Walser type.'
Context: In 1913, Walser returned to Switzerland. He lived for a short time with his sister Lisa in the mental home in Bellelay, where she worked as a teacher. There, he got to know Lisa Mermet, a washer-woman with whom he developed a close friendship. After a short stay with his father in Biel, he went to live in a mansard in the Biel hotel Blaues Kreuz. In 1914, his father died. In Biel, Walser wrote a number of shorter stories that appeared in newspapers and magazines in Germany and Switzerland and selections of which were published in Der Spaziergang (1917), Prosastucke (1917), Poetenleben (1918), Seeland (1919) and Die Rose (1925). Walser, who had always been an enthusiastic wanderer, began to take extended walks, often by night. In his stories from that period, texts written from the point of view of a wanderer walking through unfamiliar neighborhoods alternate with playful essays on writers and artists. During World War I, Walser repeatedly had to go into military service. At the end of 1916, his brother Ernst died after a time of mental illness in the Waldau mental home. In 1919, Walser's brother Hermann, geography professor in Bern, committed suicide. Walser himself became isolated in that time, when there was almost no communication with Germany because of the war. Even though he worked hard, he could barely support himself as a freelance writer. At the beginning of 1921, he moved to Bern in order to work at the public record office. He often changed lodgings and lived a very solitary life. During his time in Bern, Walser's style became more radical. In a more and more condensed form, he wrote "micrograms" ("Mikrogramme"), called thus because of his minuscule pencil hand that is very difficult to decipher. He wrote poems, prose, dramolets and novels, including The Robber (Der Rauber). In these texts, his playful, subjective style moved toward a higher abstraction. Many texts of that time work on multiple levels - they can be read as naive-playful Feuilleton or as highly complex montages full of allusions. Walser absorbed influences from serious literature as well as from formula fiction and retold, for example, the plot of a pulp novel in a way that the original (the title of which he never revealed) was unrecognizable. Much of his work was written during these very productive years in Bern.
