IN: Alexander Bell was born in Edinburgh, Scotland, on March 3, 1847. The family home was at 16 South Charlotte Street, and has a stone inscription marking it as Alexander Graham Bell's birthplace. He had two brothers: Melville James Bell (1845-70) and Edward Charles Bell (1848-67), both of whom would die of tuberculosis. His father was Professor Alexander Melville Bell, a phonetician, and his mother was Eliza Grace (nee Symonds).

By 1874, Bell's initial work on the harmonic telegraph had entered a formative stage, with progress made both at his new Boston "laboratory" (a rented facility) and at his family home in Canada a big success. While working that summer in Brantford, Bell experimented with a "phonautograph", a pen-like machine that could draw shapes of sound waves on smoked glass by tracing their vibrations. Bell thought it might be possible to generate undulating electrical currents that corresponded to sound waves. Bell also thought that multiple metal reeds tuned to different frequencies like a harp would be able to convert the undulating currents back into sound. But he had no working model to demonstrate the feasibility of these ideas. In 1874, telegraph message traffic was rapidly expanding and in the words of Western Union President William Orton, had become "the nervous system of commerce". Orton had contracted with inventors Thomas Edison and Elisha Gray to find a way to send multiple telegraph messages on each telegraph line to avoid the great cost of constructing new lines. When Bell mentioned to Gardiner Hubbard and Thomas Sanders that he was working on a method of sending multiple tones on a telegraph wire using a multi-reed device, the two wealthy patrons began to financially support Bell's experiments. Patent matters would be handled by Hubbard's patent attorney, Anthony Pollok. In March 1875, Bell and Pollok visited the scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph. Henry replied that Bell had "the germ of a great invention". When Bell said that he did not have the necessary knowledge, Henry replied, "Get it!" That declaration greatly encouraged Bell to keep trying, even though he did not have the equipment needed to continue his experiments, nor the ability to create a working model of his ideas. However, a chance meeting in 1874 between Bell and Thomas A. Watson, an experienced electrical designer and mechanic at the electrical machine shop of Charles Williams, changed all that. With financial support from Sanders and Hubbard, Bell hired Thomas Watson as his assistant, and the two of them experimented with acoustic telegraphy. On June 2, 1875, Watson accidentally plucked one of the reeds and Bell, at the receiving end of the wire, heard the overtones of the reed; overtones that would be necessary for transmitting speech. That demonstrated to Bell that only one reed or armature was necessary, not multiple reeds. This led to the "gallows" sound-powered telephone, which could transmit indistinct, voice-like sounds, but not clear speech.

What can you tell me about his discovery of the "telephone"?

IN: 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.

Did they convince people that the Soviet strategy was different?
