Question: When was the lead designer of the Lockheed Starfighter born?

full_context: Document 1: Lockheed A-12: The Lockheed A-12 was a reconnaissance aircraft built for the United States Central Intelligence Agency (CIA) by Lockheed's Skunk Works, based on the designs of Clarence "Kelly" Johnson. The aircraft was designated A-12, the 12th in a series of internal design efforts for "Archangel", the aircraft's internal code name. It competed in the CIA's "Oxcart" program against the Convair Kingfish proposal in 1959, and won for a variety of reasons.
Document 2: Jack Ridley (pilot): Colonel Jackie Lynwood "Jack" Ridley (June 16, 1915 – March 12, 1957) was an aeronautical engineer, USAF test pilot and chief of the U.S. Air Force's Flight Test Engineering Laboratory. He helped develop and test many Cold War era military aircraft but is best known for his work on the Bell X-1, the first aircraft to achieve supersonic flight. He was highly respected among fellow test pilots, most notably Chuck Yeager, for his engineering skills.
Document 3: North American P-51 Mustang: The North American Aviation P-51 Mustang is an American long-range, single-seat fighter and fighter-bomber used during World War II and the Korean War, among other conflicts. The Mustang was designed in 1940 by North American Aviation (NAA) in response to a requirement of the British Purchasing Commission. The Purchasing Commission approached North American Aviation to build Curtiss P-40 fighters under license for the Royal Air Force (RAF). Rather than build an old design from another company, North American Aviation proposed the design and production of a more modern fighter. The prototype NA-73X airframe was rolled out on 9 September 1940, 102 days after the contract was signed, and first flew on 26 October.
Document 4: Republic F-105 Thunderchief: The Republic F-105 Thunderchief was a supersonic fighter-bomber used by the United States Air Force. The Mach 2 capable F-105 conducted the majority of strike bombing missions during the early years of the Vietnam War; it was the only U.S. aircraft to have been removed from combat due to high loss rates. Originally designed as a single-seat, nuclear-attack aircraft, a two-seat Wild Weasel version was later developed for the specialized Suppression of Enemy Air Defenses (SEAD) role against surface-to-air missile sites. The F-105 was commonly known as the "Thud" by its crews.
Document 5: Lockheed F-104 Starfighter: The Lockheed F-104 Starfighter is a single-engine, supersonic interceptor aircraft which later became widely used as an attack aircraft. It was originally developed by Lockheed for the United States Air Force (USAF), but became widely used by US Allies around the world, and produced by several other NATO nations. One of the Century Series of fighter aircraft, it was operated by the air forces of more than a dozen nations from 1958 to 2004. Its design team was led by Kelly Johnson, who contributed to the development of the Lockheed P-38 Lightning, Lockheed U-2, Lockheed SR-71 Blackbird and other Lockheed aircraft.
Document 6: Lockheed SR-71 Blackbird: The Lockheed SR-71 "Blackbird" is a long-range, Mach 3+ strategic reconnaissance aircraft that was operated by the United States Air Force. It was developed as a black project from the Lockheed A-12 reconnaissance aircraft in the 1960s by Lockheed and its Skunk Works division. American aerospace engineer Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. During aerial reconnaissance missions, the SR-71 operated at high speeds and altitudes to allow it to outrace threats. If a surface-to-air missile launch was detected, the standard evasive action was simply to accelerate and outfly the missile. The SR-71 was designed with a reduced radar cross-section.
Document 7: Messerschmitt Me 163 Komet: The Messerschmitt Me 163 Komet was a German rocket-powered fighter aircraft. Designed by Alexander Lippisch, it is the only rocket-powered fighter aircraft ever to have been operational and the first piloted aircraft of any type to exceed 1000 km/h (621 mph) in level flight. Its design was revolutionary and its performance unprecedented. German test pilot Heini Dittmar in early July 1944 reached 1130 km/h , an unofficial flight airspeed record unmatched by turbojet-powered aircraft for almost a decade. Over 300 aircraft were built, but the Komet proved ineffective in its dedicated role as an interceptor aircraft and was responsible for the destruction of only about nine to eighteen Allied aircraft against ten losses. Aside from combat losses many pilots were killed during testing and training.
Document 8: General Dynamics F-16 Fighting Falcon: The General Dynamics F-16 Fighting Falcon is a single-engine supersonic multirole fighter aircraft originally developed by General Dynamics (now Lockheed Martin) for the United States Air Force (USAF). Designed as an air superiority day fighter, it evolved into a successful all-weather multirole aircraft. Over 4,500 aircraft have been built since production was approved in 1976. Although no longer being purchased by the U.S. Air Force, improved versions are still being built for export customers. In 1993, General Dynamics sold its aircraft manufacturing business to the Lockheed Corporation, which in turn became part of Lockheed Martin after a 1995 merger with Martin Marietta.
Document 9: Skunk Works: Skunk Works is an official pseudonym for Lockheed Martin's Advanced Development Programs (ADP), formerly called Lockheed Advanced Development Projects. It is responsible for a number of famous aircraft designs, including the U-2, the Lockheed SR-71 Blackbird, the Lockheed F-117 Nighthawk, Lockheed Martin F-22 Raptor, and the Lockheed Martin F-35 Lightning II, which will be used in the air forces of several countries. Its name was taken from the moonshine factory in the comic strip "Li'l Abner". The designation "skunk works" or "skunkworks" is widely used in business, engineering, and technical fields to describe a group within an organization given a high degree of autonomy and unhampered by bureaucracy, with the task of working on advanced or secret projects.
Document 10: Lockheed Martin F-22 Raptor: The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities. The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.
Document 11: Grumman F-14 Tomcat: The Grumman F-14 Tomcat is an American supersonic, twin-engine, two-seat, variable-sweep wing fighter aircraft. The Tomcat was developed for the United States Navy's Naval Fighter Experimental (VFX) program after the collapse of the F-111B project. The F-14 was the first of the American teen-series fighters, which were designed incorporating air combat experience against MiG fighters during the Vietnam War.
Document 12: William J. Knight: William John "Pete" Knight (November 18, 1929 – May 7, 2004), (Col, USAF), was an American aeronautical engineer, politician, Vietnam War combat pilot, test pilot, and astronaut in the X-20 Dyna-Soar and North American X-15 programs. Knight holds the world's speed record for flight in a winged, powered aircraft.
Document 13: Chuck Yeager: Charles Elwood "Chuck" Yeager ( ; born February 13 , 1923) is a former United States Air Force general officer and record-setting test pilot. In 1947, he became the first pilot confirmed to have exceeded the speed of sound in level flight.
Document 14: Charlie Johnson (pilot): Charles (Charlie) Johnson is a former president of Cessna Aircraft. He was born in 1942 in Georgia and grew up in Memphis. He has always been passionate about technology. Because he was also passionate about flight, he joined the Air Force. He fought in the Vietnam War flying the T-33, T-37, T-38, and the F-105. After the Vietnam War he continued with his love of flying. Johnson was a personal pilot for Arnold Palmer. After this he became a test pilot for Learjet. Soon after he rose through the ranks of Cessna to President and COO of Cessna Aircraft. Johnson joined Bye Aerospace in 2014 and was inducted into the Colorado Aviation Hall of Fame the same year. He has just recently been inducted into the Kansas Aviation Hall of Fame. Johnson continues to fly and has a love of cars.
Document 15: Kelly Johnson (engineer): Clarence Leonard "Kelly" Johnson (February 27, 1910 – December 21, 1990) was an American aeronautical and systems engineer. He is recognized for his contributions to a series of important aircraft designs, most notably the Lockheed U-2 and SR-71 Blackbird. Besides the first production aircraft to exceed Mach 3, he also produced the first fighter capable of Mach 2, the United States' first operational jet fighter, as well as the first U.S. fighter to exceed 400 mph, and many other contributions to a large number of aircraft. As a member and first team leader of the Lockheed Skunk Works, Johnson worked for more than four decades and is said to have been an "organizing genius". He played a leading role in the design of over forty aircraft, including several honored with the prestigious Collier Trophy, acquiring a reputation as one of the most talented and prolific aircraft design engineers in the history of aviation. In 2003, as part of its commemoration of the 100th anniversary of the Wright Brothers' flight, "Aviation Week & Space Technology" ranked Johnson 8th on its list of the top 100 "most important, most interesting, and most influential people" in the first century of aerospace. Hall Hibbard, Johnson's Lockheed boss, referring to Johnson's Swedish ancestry once remarked to Ben Rich: "That damned Swede can actually see air."
