Dan Olmsted (1954?-2017) was a journalist and former senior editor for United Press International (UPI), a news agency of the Unification Church company News World Communications. Olmsted wrote a series of reports suggesting a link between vaccination and autism, a hypothesis which has been disproven. His columns on health and medicine appeared regularly in The Washington Times and were syndicated nationally from UPI's Washington D.C. bureau. He owned and edited the Age of Autism website, a site he described as the "Daily Web Newspaper of the Autism Epidemic", where writers question the safety of vaccines. Olmsted wrote an article in 2002, along with reporter Mark Benjamin, which drew links between the drug Lariam given to military personnel and mental health disorders in soldiers.He co-wrote four books with Mark Blaxill, co-founder of Age of Autism. The last, Denial: How Refusing to Face the Facts about Our Autism Epidemic Hurts Children, Families, and Our Future was released posthumously in 2017.
