Who developed Hydrogen Bomb?

Edward Teller, a Hungarian-American physicist, is widely known as the "Father of the Hydrogen Bomb" — a title that followed him throughout his entire life, though he himself had complicated feelings about it. While J. Robert Oppenheimer led the Manhattan Project that developed the atomic bomb, it was Teller who championed and spearheaded the development of the far more powerful thermonuclear weapon, commonly known as the Hydrogen Bomb. The H-bomb works on the principle of nuclear fusion — the same process that powers the sun — making it thousands of times more powerful than the atomic bombs dropped on Hiroshima and Nagasaki.

• Principle: Hydrogen bomb works on nuclear fusion — lighter hydrogen nuclei fuse together to release enormous energy, unlike atomic bombs that use fission
• Teller-Ulam Design: The breakthrough came in 1951 when Teller and Stanislaw Ulam together developed the two-stage radiation implosion design that made H-bomb practical
• First Test: The first successful hydrogen bomb test — codenamed Ivy Mike — was conducted by the United States on November 1, 1952
• Power: Ivy Mike explosion yielded 10.4 megatons — approximately 700 times more powerful than the Hiroshima atomic bomb
• Others: Oppenheimer led atomic bomb development, Von Braun developed rocket technology, and Samuel Cohen invented the neutron bomb — none developed the hydrogen bomb
