A bulldozer kills Rev. Bruce W. Klunder, a civil rights activist, during a school segregation protest in Cleveland, Ohio, sparking a riot.
Reverend Bruce W. Klunder (July 12, 1937 April 7, 1964) was a Presbyterian minister and civil rights activist, born in Colorado, United States. He died when he was run over by a bulldozer while protesting the construction of a segregated school in Cleveland, Ohio. Klunder graduated in science from Oregon State University in 1958. While attending the school, he met his future wife, Joanne Lehman. The couple married December 22, 1956. He went on to earn his Bachelor of Divinity from Yale Divinity School in 1961. After college, Klunder and his wife moved to Cleveland where he was hired as assistant executive secretary of the Student Christian Union at Western Reserve University. He quickly became involved in the city's civil rights fight. He had a passionate interest in civil rights, headed the local chapter of the Congress of Racial Equality (CORE), and led a restaurant sit-in in Sewanee, Tennessee, in 1962. He and his wife had two young children at the time.
A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks, though specialized models riding on large off-road tires are also produced.
Its most popular accessory is a ripper, a large hook-like device mounted singly or in multiples in the rear to loosen dense materials.
Bulldozers are used heavily in large and small scale construction, road building, minings and quarrying, on farms, in heavy industry factories, and in military applications in both peace and wartime.
The word "bulldozer" refers only to a motorized unit fitted with a blade designed for pushing. The word is sometimes used inaccurately for other heavy equipment such as a front-end loader designed for carrying rather than pushing material.
