Leonardo di ser Piero da Vinci (Italian: [leo'nardo di ,ser 'pje:ro da (v)'vintSi] ( listen); 15 April 1452 - 2 May 1519), more commonly Leonardo da Vinci or simply Leonardo, was an Italian Renaissance polymath whose areas of interest included invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time. Sometimes credited with the inventions of the parachute, helicopter and tank, he epitomised the Renaissance humanist ideal.
In 1466, at the age of fourteen, Leonardo was apprenticed to the artist Andrea di Cione, known as Verrocchio, whose bottega (workshop) was "one of the finest in Florence". He apprenticed as a garzone (studio boy) to Andrea del Verrocchio, the leading Florentine painter and sculptor of his day (and would do so for 7 years). Other famous painters apprenticed or associated with the workshop include Domenico Ghirlandaio, Perugino, Botticelli, and Lorenzo di Credi. Leonardo would have been exposed to both theoretical training and a vast range of technical skills, including drafting, chemistry, metallurgy, metal working, plaster casting, leather working, mechanics and carpentry as well as the artistic skills of drawing, painting, sculpting and modelling.  Much of the painted production of Verrocchio's workshop was done by his employees. According to Vasari, Leonardo collaborated with Verrocchio on his The Baptism of Christ, painting the young angel holding Jesus' robe in a manner that was so far superior to his master's that Verrocchio put down his brush and never painted again, although this is believed to be apocryphal. Close examination reveals areas that have been painted or touched-up over the tempera using the new technique of oil paint; the landscape, the rocks seen through the brown mountain stream and much of the figure of Jesus bearing witness to the hand of Leonardo. Leonardo may have been the model for two works by Verrocchio: the bronze statue of David in the Bargello and the Archangel Raphael in Tobias and the Angel.  By 1472, at the age of twenty, Leonardo qualified as a master in the Guild of Saint Luke, the guild of artists and doctors of medicine, but even after his father set him up in his own workshop, his attachment to Verrocchio was such that he continued to collaborate with him. Leonardo's earliest known dated work is a drawing in pen and ink of the Arno valley, drawn on 5 August 1473.

Who else

Lorenzo di Credi.

Richard Edgar Pipes (born July 11, 1923) is a Polish-American academic who specializes in Russian history, particularly with respect to the Soviet Union, who espoused a strong anti-communist point of view throughout his career. In 1976 he headed Team B, a team of analysts organized by the Central Intelligence Agency who analyzed the strategic capacities and goals of the Soviet military and political leadership. Pipes is the father of American historian and expert on American foreign policy and the Middle East, Daniel Pipes. Pipes was born to a Jewish family in Cieszyn, Poland, which fled the country as refugees after it was invaded by Nazi Germany.
Pipes was head of the 1976 Team B, composed of civilian experts and retired military officers and agreed to by then-CIA director George H. W. Bush at the urging of the president's Foreign Intelligence Advisory Board (PFIAB) as a competitive analysis exercise. Team B was created at the instigation of then Secretary of Defense Donald Rumsfeld as an antagonist force to a group of CIA intelligence officials known as Team A. His hope was that it would produce a much more aggressive assessment of Soviet Union military capabilities. Unsurprisingly, it argued that the National Intelligence Estimate on the Soviet Union, generated yearly by the CIA, underestimated both Soviet military strategy and ambition and misinterpreted Soviet strategic intentions.  Team B faced criticism. The international relations journalist Fred Kaplan writes that Team B "turns out to have been wrong on nearly every point." Pipes's group insisted that the Soviet Union, as of 1976, maintained "a large and expanding Gross National Product," and argued that the CIA belief that economic chaos hindered the USSR's defenses was a ruse on the part of the USSR. One CIA employee called Team B "a kangaroo court".  Pipes called Team B's evidence "soft." Team B came to the conclusion that the Soviets had developed several new weapons, featuring a nuclear-armed submarine fleet that used a system that did not depend on active sonar, and was thus undetectable by existing technology.  According to Pipes, "Team B was appointed to look at the evidence and to see if we could conclude that the actual Soviet strategy is different from ours, i.e. the strategy of Mutual Assured Destruction (MAD). It has now been demonstrated totally that it was". In 1986, Pipes maintained that Team B contributed to creating more realistic defense estimates.

What did Team B do?
