Q: Question: How many other recipients were there of the United States Eisenhower Fellowships in the year 2006? Passage 1:Caracciola began racing while he was working as apprentice at the Fafnir automobile factory in Aachen during the early 1920s, first on motorcycles and then in cars. Racing for Mercedes-Benz, he won his first two Hillclimbing Championships in 1930 and 1931, and moved to Alfa Romeo for 1932, where he won the Hillclimbing Championship for the third time. In 1933, he established the privateer team Scuderia C.C. with his fellow driver Louis Chiron, but a crash in practice for the Monaco Grand Prix left him with multiple fractures of his right thigh, which ruled him out of racing for more than a year. He returned to the newly reformed Mercedes-Benz racing team in 1934, with whom he won three European Championships, in 1935, 1937 and 1938. Like most German racing drivers in the 1930s, Caracciola was a member of the Nazi paramilitary group National Socialist Motor Corps (NSKK), but never a member of the Nazi Party. He returned to racing after the Second World War, but crashed in qualifying for the 1946 Indianapolis 500. A second comeback in 1952 was halted by another crash, in a sports car race in Switzerland.

Her niece, Anne Neville (youngest daughter of the "Kingmaker") would become Queen of England as the consort of Richard III; Katherine's sister Alice, Baroness FitzHugh, and her other niece, Elizabeth FitzHugh, were personally selected as Anne's chief ladies-in-waiting. Her paternal grandparents were Ralph Neville, 1st Earl of Westmorland and Joan Beaufort, Countess of Westmoreland, a daughter of John of Gaunt by his third wife, Katherine de Roët, making her a direct descendant of Edward III.
