Humans have been using lead for over 5000 years. However, since the time of Hippocrates, which was about 2600 years ago and maybe earlier, an awareness of the toxicity from lead was known. More recently in the mid 1800’s Charles Dickens wrote about lead poisoning in his book The Unconventional Traveler, and in the late 1800’s the U.S. medical authorities were talking about lead poisoning in children. In 1910
Dr. Alice Hamilton wrote about lead poisoning in Illinois factories. Hamilton’s work essentially gave birth to the field of Industrial Toxicology. Despite this work by Hamilton and others about the dangers of lead, and despite the League of Nations declaring a ban on interior lead paint in the early 1920’s, the use of lead (tetraethyl lead) as an additive to gasoline to prevent engine knocking was accelerating. It wasn’t until the 1970’s that the U.S. banned the use of lead in paint and gasoline. Much of the credit at that time is due to Dr. Philip Landrigan, an epidemiologist and pediatrician who had studied lead poisoning from lead refineries and gasoline. Landrigan is known as one of the leading scientists advocating for children’s health. He has written several books about raising children toxin free (from lead, asbestos, and pesticides) and authored over 500 scientific papers.
