When people, especially children, ingest small amounts of lead over a period of time—by drinking contaminated water, breathing contaminated air, or accidently eating leaded paint chips—they can become very sick.

The Brooklyn Subcommittee on Lead Poisoning was one of many local groups that worked to educate citizens on the dangers of lead. About 100 community workers from various anti-poverty agencies and community organizations in the Bedford-Stuyvesant neighborhood attended this lead poisoning seminar.

Physician and industrial health pioneer, Alice Hamilton, became interested in lead poisoning and the health of workers while living at Hull-House, a settlement house in Chicago that provided social services to the city’s immigrant community. She published investigative reports about the dangers of lead poisoning faced by workers in several industries.

Industrial health pioneer Alice Hamilton published investigative reports about the dangers of lead poisoning faced by workers in several industries. Among the dangerous trades highlighted was printing.
Printers used lead-based metal type. With bare hands, workers manipulated individual “slugs” or pieces of metal used for spacing. Workers were exposed to lead dust and fumes created by the printing machines.

The glazes used to coat ceramics contained lead. When workers fired the pottery, lead fumes entered the air in the factory. Workers inhaled the toxic vapors, which caused severe respiratory issues.

Cardiovascular physiologist Yandell Henderson was a director of the Yale Laboratory of Applied Physiology and a leading expert on poison gases and automotive exhaust. Yandell Henderson recognized the dangers of and opposed the use of tetraethyl lead in gasoline in the 1920s. He asserted leaded gas was “worse than tuberculosis,” one of the leading causes of death at the time. Throughout the 1920s, newspapers reported on serious, and sometimes fatal, cases of lead poisoning in oil refinery workers.

Clair Patterson, a pioneering geochemist at the California Institute of Technology, helped develop a technique used to calculate the age of the earth using lead isotopes. After encountering lead contamination in his research, he spent years collecting data and pushing for legislation to reduce lead in the environment.

In the 1960s and 1970s, geochemist Clair Patterson gathered evidence that proved the pervasiveness of lead contamination. Patterson’s rigorous data collection and advocacy led to life-saving reductions in environmental lead.

Amendments to the 1970 Clean Air Act resulted in the elimination of leaded gasoline in the U.S. by the late 1980s. Once a common sight to drivers, leaded gasoline pumps would fade into history.

Manufacturers added leaded pigments to paint to improve durability and drying time. Toys like the ones shown here were toxic because of the lead used in the paint. Children could easily ingest lead by putting toys in their mouth.

For over 50 years, the National Lead Company used the image of a happy, healthy, and fictional Dutch Boy to market lead paints as safe and wholesome. Dutch Boy ads targeted children with friendly coloring paint books. Here, the Dutch Boy is having fun riding a toy “lead” horse and is ready to be helpful with chores by carrying a paint brush.

Dutch Boy ads from the National Lead Company promoted lead paint products to families. This image shows a painter prescribing pure lead for all household painting using a medical reference—the Dutch Boy by his side.

This advertisement falsely reassured parents that leaded paint was safe for children and families. The message “lead helps to guard your health” responded to growing public concern over lead’s toxicity in industrial trades and paint products, as described by industrial health pioneer Alice Hamilton.

Storage batteries provide a rechargeable source of energy for passenger cars, trains, streetcars, and lamps. In the past, manufacturers often removed the lead plates in the batteries and discarded empty casings in poor neighborhoods to minimize disposal costs. These self-contained casings, which were made of hard rubber, emitted intense heat when burned.
Exide batteries were similar to those dumped by the Bruco Company in a Chicago neighborhood in 1959.

Physician activist Alice Hamilton called battery manufacturing a very dangerous trade for workers. The absence of safety regulations and adequate worker protections against lead poisoning was a serious public health threat.

Newspapers reported stories about the deadly results of the illegally dumped battery casings. Children died or were poisoned from breathing toxic lead sulphate. Officials retrieved over 2,000 casings.

The Student Organization for Urban Leadership formed in 1964 to combat lead poisoning. Members distributed pamphlets, gathered paint samples, and collected urine of children for testing.

Movements in Chicago and other cities led to increased governmental action, including publications that warned parents of lead in homes.

The Flake and His Secret Plan was distributed by the government to warn the public about the danger of household lead paint. This comic book told a story about an evil flake of paint and included a short list of ways to reduce the threat of lead paint.
