Napalm, incendiary gel that sticks to skin and burns to the bone, came into the world on Valentine’s Day 1942 at a secret Harvard war research laboratory. On March 9, 1945, it created an inferno that killed over 87,500 people in Tokyo—more than died in the atomic explosions at Hiroshima or Nagasaki. It went on to incinerate sixty-four of Japan’s largest cities. The Bomb got the press, but napalm did the work.

After World War II, the incendiary held the line against communism in Greece and Korea—Napalm Day led the 1950 counter-attack from Inchon—and fought elsewhere under many flags. Americans generally applauded, until the Vietnam War. Today, napalm lives on as a pariah: a symbol of American cruelty and the misguided use of power, according to anti-war protesters in the 1960s and popular culture from Apocalypse Now to the punk band Napalm Death and British street artist Banksy. Its use by Serbia in 1994 and by the United States in Iraq in 2003 drew condemnation. United Nations delegates judged deployment against concentrations of civilians a war crime in 1980. After thirty-one years, America joined the global consensus, in 2011.

Robert Neer has written the first history of napalm, from its inaugural test on the Harvard College soccer field, to a Marine Corps plan to attack Japan with millions of bats armed with tiny napalm time bombs, to the reflections of Phan Thi Kim Phuc, a girl who knew firsthand about its power and its morality.

When President Eisenhower referred to the "military-industrial complex" in his 1961 Farewell Address, he summed up in a phrase the merger of government and industry that dominated the Cold War United States. In this bold reappraisal, Katherine Epstein uncovers the origins of the military-industrial complex in the decades preceding World War I, as the United States and Great Britain struggled to perfect a crucial new weapon: the self-propelled torpedo.

Torpedoes epitomized the intersection of geopolitics, globalization, and industrialization at the turn of the twentieth century. They threatened to revolutionize naval warfare by upending the delicate balance among the world's naval powers. They were bought and sold in a global marketplace, and they were cutting-edge industrial technologies. Building them, however, required substantial capital investments and close collaboration among scientists, engineers, businessmen, and naval officers. To address these formidable challenges, the U.S. and British navies created a new procurement paradigm: instead of buying finished armaments from the private sector or developing them from scratch at public expense, they began to invest in private-sector research and development. The inventions emerging from torpedo R&D sparked legal battles over intellectual property rights that reshaped national security law.

Blending military, legal, and business history with the history of science and technology, Torpedo recasts the role of naval power in the run-up to World War I and exposes how national security can clash with property rights in the modern era.
