Harold Camping was born on July 19, 1921, in Boulder, Colorado, and was raised in the Christian Reformed Church. He earned a degree in civil engineering from the University of California, Berkeley, in 1942, and worked as an engineer for a government contractor for the duration of World War II. After the war, he established a construction business in California.
In 1958, Camping transitioned into religious broadcasting. He partnered with individuals from Christian Reformed, Bible Baptist, and conservative Presbyterian backgrounds to purchase KEAR, an FM radio station in San Francisco. This acquisition became the foundation for Family Stations, Incorporated, later known as Family Radio. The network was initially intended to broadcast Christian programming to Protestant audiences.
During the 1960s and following decades, Family Radio expanded by acquiring additional stations. At its peak, the network broadcast in more than 150 markets across the United States and operated an international shortwave service reaching countries including Taiwan and Ghana. Over time, it developed into a media enterprise valued at approximately $100 million.
In 1961, Family Radio launched “Open Forum,” a live call-in program hosted by Camping. The program aired on weeknights and became the primary platform for his teachings over the next five decades. Listeners called in with questions about the Bible, and Camping responded using an interpretive method based on cross-referencing scripture. The program was translated into multiple languages and distributed globally through shortwave radio, cable television, and the internet.
Camping’s theological views diverged over time from those of traditional Christian denominations. In 1988, he left the Christian Reformed Church. That same year, Camping declared that the “Church Age” had ended. He stated that the Holy Spirit had departed from all organized churches, rendering them invalid. He instructed followers to leave their congregations and rely on personal Bible study and Family Radio broadcasts instead.
This directive, combined with the central role of Camping’s interpretations, later led to allegations that the group functioned as a closed system. Followers were encouraged to disengage from external religious institutions, limiting exposure to alternative viewpoints. Although Camping did not claim formal clerical authority and stated that Family Radio was not a church, his interpretations were treated by followers as authoritative.
Camping’s focus on biblical chronology began in the 1970s. In 1970, he published The Biblical Calendar of History, followed by Adam When? in 1974. These works placed the creation of the world at 11,013 BCE and the biblical flood at 4990 BCE. His calculations departed from earlier chronologies, including those of Bishop James Ussher. Camping developed a system based on reinterpretation of genealogical language in the Old Testament, which formed the basis for later predictions.
In 1992, Camping published 1994?, which proposed that the Second Coming and the Rapture might occur on September 6, 1994. The book allowed for uncertainty but generated concern among followers. When the date passed without incident, Camping revised the prediction to September 29 and then October 2. The failure of these predictions led to criticism from other Christian leaders, who rejected his interpretive approach.
Reports from within the organization indicated that some followers made significant financial decisions based on these predictions, including selling property and donating savings. Internal accounts also indicated that requests for refunds were not granted. Despite these developments, Family Radio continued operating and maintained an audience.
In 2005, Camping announced a new prediction, stating that the Rapture would occur on May 21, 2011. He described a subsequent five-month period of global suffering, ending with the destruction of the world on October 21, 2011. Family Radio supported this announcement with a large-scale international campaign, funded in part through the sale and exchange of broadcast assets.
The campaign included billboards, traveling promotional vehicles, and the distribution of approximately 100 million pamphlets in 61 languages. The effort drew attention from both religious organizations and the general public. Some followers made major personal and financial changes in response, including leaving jobs and using personal funds to promote the message. A case was reported in which a teenager in Russia died by suicide after exposure to the campaign.
When May 21, 2011 passed without the predicted events, Camping temporarily withdrew from public view. On May 23, he returned and stated that a spiritual judgment had occurred on the predicted date, with the physical end of the world still expected on October 21. He also confirmed that donations received during the campaign would not be returned.
The failure of the October 21, 2011 prediction led to a significant decline in Camping’s public presence. This decline was compounded by a stroke he suffered in June 2011. “Open Forum” was discontinued, and attendance at his local fellowship decreased substantially. In March 2012, Camping issued a public statement acknowledging that his attempts to predict the end of the world were incorrect and described them as sinful. He stated that the timing of such events could not be known. After this statement, he withdrew from public life.
Camping died on December 15, 2013, at the age of 92, following complications from a fall at his home in Alameda, California.
In October 2018, under new leadership, Family Radio discontinued all programming based on Camping’s teachings. The organization issued a public statement distancing itself from prior date-setting practices and its earlier stance toward other churches, and it shifted its programming toward standard evangelical content.
