Question: The 1972 German Grand Prix ended with which Swiss driver finishing 2nd?
Context: The 1972 German Grand Prix was a Formula One motor race held at Nürburgring on 30 July 1972.  It was race 8 of 12 in both the 1972 World Championship of Drivers and the 1972 International Cup for Formula One Manufacturers.  The 14-lap race was won by Ferrari driver Jacky Ickx after he started from pole position.  His teammate Clay Regazzoni finished second and March driver Ronnie Peterson came in third. The 2013 German Grand Prix (formally known as the Formula 1 Großer Preis Santander von Deutschland 2013) was a Formula One motor race that was held on 7 July 2013 at the Nürburgring in Nürburg, Germany.  The race was the ninth round of the 2013 season, and marked the 74th running of the German Grand Prix overall, and the 60th running of the German Grand Prix since 1950, when the racing series now known as the Formula One World Championship was created.  This is the earliest a German Grand Prix has been held in a calendar year, followed by the 1926 and the 2009 editions of the race. Gianclaudio Giuseppe Regazzoni (5 September 1939 – 15 December 2006), commonly called "Clay", was a Swiss racing driver.  He competed in Formula One races from 1970 to 1980, winning five Grands Prix.  His first win was the Italian Grand Prix at Monza in his debut season, driving for Ferrari.  He remained with the Italian team until .  After a single season with BRM, Regazzoni returned to Ferrari for a further three years, to .  After finally leaving Ferrari at the end of 1976, Regazzoni joined the Ensign and Shadow teams, before moving to Williams in , where he took the British team's first ever Grand Prix victory, the 1979 British Grand Prix at Silverstone. The Klenk-Meteor was a racing car which competed in the 1954 German Grand Prix.  The car was based on the established German marque of Veritas which was active between 1948 and 1953.  Veritas is chiefly remembered as a manufacturer of sports cars and successful Formula Two racing cars.  The company closed when its founder, Ernst Loof, became ill.  He subsequently died in 1956.  The Klenk-Meteor entered for the 1954 German Grand Prix was essentially a Veritas Formula Two car.  The car was owned and prepared by the noted German racing driver Hans Klenk who intended to race it himself in the Grand Prix.  However, Klenk's career as a racing driver came to an end when he suffered injuries in an accident while working as a test driver for Mercedes-Benz.  The car was driven in the Grand Prix by another German, Theo Helfrich.  He retired on lap 9 with engine failure. The 1939 Grand Prix season was the seventh AIACR European Championship season.  The championship winner was never officially announced by the AIACR due to the outbreak of World War II less than two weeks after the final event in Switzerland.  The Italian GP initially had been a fifth event, but it became clear well before the war that it would be cancelled due to construction work.  At that time, it was also undecided which scoring system would be used, the old minimum points system that basically counted positions, or the French maximum points system similar to the modern one.  Although Hermann Paul Müller would have won the championship on points according to the old system, the president of Nazi Germany's highest motorsports organisation declared Hermann Lang the champion.  Lang was clearly the dominating driver in that season, which was acknowledged by the international press.  In the first two of the four championship events, both Lang and Müller won once while the other failed to complete 75% of the distance.  The German round saw Lang retiring early, and Müller finishing 2nd behind Carraciola.  This left Müller in the lead in both scoring systems, as published in magazines, with the Swiss round deciding the outcome.  Müller finished 4th behind three Mercedes, which gave him the lead in the old point system, while in front, Lang had beaten Carraciola for the lead in the maximum points system. The 1974 German Grand Prix was a Formula One motor race held at the Nürburgring on 4 August 1974.  It was race 11 of 15 in both the 1974 World Championship of Drivers and the 1974 International Cup for Formula One Manufacturers.  It was the 36th German Grand Prix and the 33rd to be held at the Nürburgring complex of circuits.  The race was won by Swiss driver Clay Regazzoni driving a Ferrari 312B3.  Regazzoni led every lap on the way to his second Grand Prix victory, some four years after his debut victory at the 1970 Italian Grand Prix.  South African driver Jody Scheckter was second driving a Tyrrell 007 ahead of Argentine driver Carlos Reutemann (Brabham BT44). Hideo Kanaya (Shinjitai: 金谷 秀夫 , Hideo Kanaya , February 3, 1945 – December 19, 2013) was a Grand Prix motorcycle road racer from Japan.  Kanaya began his Grand Prix career in 1967 and won his first Grand Prix at the 1972 250cc German Grand Prix.  In 1972, Kanaya and Jarno Saarinen raced the first four-cylinder, two-stroke Yamaha TZ 500 in the 500cc world championship.  After Saarinen's death in the 250cc race at the Italian Grand Prix at Monza, the TZ 500 project was put aside and Kanaya raced only in the 250cc class.  Kanaya's best season was in 1975, when he finished third in the 500cc world championship behind his Yamaha team-mate, Giacomo Agostini and MV Agusta's Phil Read.  He also won the Macau Grand Prix in 1975. Börje Jansson (born November 10, 1942 ) was a former Grand Prix motorcycle road racer from Sweden.  His best years were in 1971 and 1972, when he finished third in the 125cc world championship riding for the Maico factory racing team.  He won the 1972 125cc East German Grand Prix, marking the first Grand Prix road racing victory for the German motorcycle manufacturer.  Jansson won four Grand Prix races in his career.  Jansson is the only rider in history to win a Grand Prix riding the Derbi 250 twin (1972 Austrian Grand Prix at the Salzburgring), out of only two races with the Spanish machine. The 1968 Grand Prix motorcycle racing season was the 20th F.I.M. Road Racing World Championship Grand Prix season.  The season consisted of ten Grand Prix races in six classes: 500cc, 350cc, 250cc, 125cc, 50cc and Sidecars 500cc.  It began on 21 April, with German Grand Prix and ended with Nations Grand Prix on 15 September.  As the sidecar race was cancelled at the Nations Grand Prix, it was announced that a replacement race would be held at Hockenheimring in October alongside the German national championship. The 1959 German Grand Prix was a Formula One motor race held at the Automobil-Verkehrs- und Übungs-Straße in West Berlin on 2 August 1959.
