The Trinity Test
July 16, 1945

At 5:29 AM on July 16, 1945, an enormous explosion rocked the bleak desert of southern New Mexico. The cause of the blast was a device called the Gadget, which exploded with the force of forty million pounds of TNT. It produced intense heat, a light brighter than the sun, and a mushroom cloud 7.5 miles high that glowed yellow, then red, then purple. People felt the shockwave 100 miles from ground zero, and newspapers reported that a blind woman 150 miles away asked: “What’s that brilliant light?”

Margaret Truman Daniel—A Unique Privilege

ON FEBRUARY 17, 1924—a wintry Missouri day—Harry and Bess Truman celebrated the birth of their daughter.

Two years earlier, Harry Truman’s haberdashery business in downtown Kansas City, Missouri, had failed.
