Albert Berry jumps from a biplane traveling at 1,500 feet and lands by parachute at Jefferson Barracks, Missouri. The 36 foot diameter chute was contained in a metal canister attached to the underside of the plane, and when Berry dropped from the plane his weight pulled the canopy from the canister. Rather than being secured into the chute by a harness, Berry was seated on a trapeze bar. It's possible he was only the second man to accomplish a parachute landing, as there are some accounts of someone accomplishing the feat in California several months earlier.

The twenty-month-old son of aviator Charles Lindbergh, Charles Augustus Lindbergh III, is kidnapped from the family home in East Amwell, New Jersey. Over two months later the toddler's body is discovered in woods a short distance from the home. A medical examination determines that he had died of a massive skull fracture. A German carpenter named Bruno Hauptmann is arrested, tried, and convicted for the crime. He is sentenced to death and executed in April 1936.

American biologists James D. Watson and Francis Crick tell their friends that they have determined the chemical structure of DNA. The formal announcement takes place in April following publication in Nature magazine. In 1968, Watson writes The Double Helix, a non-fiction account of not only the discovery of the structure of DNA, but the personalities, conflicts and controversy surrounding the work.

In the United States, a conservative legal challenge to the nineteenth amendment to the U.S. Constitution establishing voting rights for women is rebuffed by the Supreme Court in Leser v. Garnett. The challenge was based partly on the idea of individual "states rights" to self determination. The failure of such reasoning as it applied to basic human rights created a framework for later states rights losses involving the denial of voting rights to African-Americans.
