President Theodore Roosevelt signs the Pure Food and Drugs Act into law, the first federal legislation calling for stricter labeling of U.S. food and drug products. The act prevents the production and trafficking of mislabeled, adulterated, or poisonous foods, pharmaceuticals, patent medicines and liquors, and paves the way for the modern Food and Drug Administration.
Twelve years after discovering radium chloride, Marie and Pierre Curie isolate a gram of pure radium. The discovery leads to innovations in cancer treatments and the coinage of a new word: radioactivity.
In popular culture, Radium is touted as health additive and miracle cure for ailments from rheumatism to appendicitis; women buy radium-based facial creams, children enjoy radium-laced candy and soda, and clinics offer free injections of the new wonder drug.

Fremont and Annie Jackson are discovered dead inside their locked Manhattan apartment. Though police initially suspect a dual suicide, Charles Norris and Alexander Gettler find cyanide in the victims lungs and police suspect a recent fumigation in the building caused the couple's untimely death.
When prosecutors lose the case in court, Gettler is inspired to do further research. He will publish "The Toxicology of Cyanide" in 1938 -- a text still referenced nearly century later.
General Motors and its part-owner DuPont aligns with Standard Oil Company to market leaded gasoline in conjunction with the Ethyl Corporation. The new leaded gas allows car engines to run more smoothly and quietly.
When workers at Standard Oil's tetraethyllead plant in Bayway, New Jersey (in the "looney gas building") begin to show signs of mental deterioration, the Public Health Service makes an inquiry, but determines that the additive posed no serious threat to the public. Leaded gasoline will be used to fuel cars until 1996, when the Environmental Protection Agency will fully phase out its use.
In 1925, 4,154 people die from poisoned liquor, up from 1,064 in 1920.
An investigative task force called by the U.S. Surgeon General releases its finding that leaded gasoline is essentially safe, provided workers use the recommended precautions such as gloves and masks.
Newspaper articles cite quotes from government officials warning of increased toxicity in bootlegged alcohol. In an effort to enforce Prohibition, the United States government researches more poisonous chemicals, such as kerosene, acetone and formaldehyde, to use to denature alcohol, to prevent consumption. But that does not stop tens of thousands of people from drinking it, often with fatal consequences.
Francesco Travia is caught lugging part of Anna Fredericksen's body towards the waterfront. Detectives suspect murder, but Charles Norris and Alexander Gettler prove that the carbon monoxide gas from Travia's stove had poisoned her to death. Travia will serve time for illegally disposing of a body.
After 112 holiday revelers are hospitalized or killed by poisoned liquor Charles Norris issues a harshly-worded public statement denouncing the government for deliberately adding poisons to alcohol: “The United States government must be charged with the moral responsibility for the deaths that poisoned liquor causes.”

The Stock Market crashes, sending the economy into a depression. By the end of 1930 over four million Americans will be unemployed. In New York City, murder by poison becomes a more common crime.
Durable Mike Malloy finally succumbs to death from carbon monoxide poisoning. A group of men hoping to collect on Malloy's life insurance policy had attempted to poison the homeless alcoholic on several occasions by using wood alcohol, methanol, ethylene glycol (antifreeze), arsenic, and food poisoning, as well as by trying to freeze him to death and by hitting him with a car. The men finally succeeded in murdering Malloy by connecting a hose from a gas jet to the passed-out Malloy's mouth.
Malloy would become an iconic figure of The Great Depression.
