Farquharson</abstract></did><bioghist encodinganalog="5451_"><p>The Engineering Experiment Station of the University of Washington was
		  officially established by the Board of Regents in 1917. The express purpose of
		  the Station was "to aid in the industrial development of the state and nation
		  by scientific research and by furnishing information for the solution of
		  engineering problems." The Station had 3 directors during its existence, Carl
		  Edward Magnusson from 1917 until his death in 1941, Edgar Allan Loew from 1941
		  to 1945, and Frederick Burt Farquharson from 1945 to 1963. In September of
		  1962, the Office of Engineering Research was established within the College of
		  Engineering for the promotion and administration of sponsored research in the
		  various engineering departments. In July of 1963, the Engineering Experiment
		  Station was merged with the Office of Engineering Research under the latter
		  title.</p><p>From its inception in 1917 to its end in 1963, the Station performed
		  research in many areas of engineering and science. The Station conducted
		  research for a wide range of civil and private organizations, both within and
		  outside of the United States. The list of clients includes the United States
		  Department of the Interior, Washington State, the City of Seattle, the City of
		  Vancouver British Columbia, and a number of private companies. Perhaps the
		  Station's most notable work was an investigation of the Tacoma Narrows Bridge
		  collapse in 1940. Much of the research on this problem was led by Frederick
		  Burt Farquharson. Professor Farquharson received publicity for his construction
		  of a quonset-hut wind tunnel, which he used to test full and sectional models
		  of the bridge, simulating the violent winds that rocked "Galloping Gertie."</p><p>The original Tacoma Narrows Bridge was built between November 1938 and
		  July 1, 1940. Lauded as an essential economic and military portal to the
		  Olympic peninsula, its completion was called a triumph of man's ingenuity and
		  perseverance. Four months after it opened to the public, it collapsed in what
		  was later called "the Pearl Harbor of engineering."</p><p>Contemporary accounts appeared to be shocked by the collapse, although
		  the bridge had begun exhibiting wavelike motions during the final stages of
		  construction. Soon after its official opening, the bridge gained a reputation
		  for this movement and was informally christened "Galloping Gertie." Professor
		  F.B. Farquharson, an engineering professor at the University of Washington, and
		  other University engineers were hired to suggest methods to reduce the movement
		  on the bridge. Over the next few months experiments were conducted on a scale
		  model, but a solution to the problem proved elusive.</p><p>On November 7, 1940, Professor Farquharson was there to witness and
		  document the spectacular collapse of what had been the third longest suspension
		  bridge in the world with the longest single span in the country. In the
		  aftermath, many theories were discussed concerning the cause of the bridge's
		  collapse. Ultimately an investigative board for the Washington State Toll
		  Bridge Authority announced the failure was due to the bridge's design reacting
		  to the wind in the Narrows.</p><p>Although rebuilding the bridge was immediately suggested,
		  investigations on the wreckage found the entire superstructure to be unusable.
		  The onset of World War II further stalled attempts to rebuild. Salvage activity
		  continued on the bridge through 1942 with the materials going to the U.S. war
		  effort and the profits saved for the construction of a new bridge.</p><p>While the salvage work went on, Professor Farquharson was commissioned
		  to test models of the old Narrows Bridge and the new proposed design for the
		  bridge. At the University of Washington's new structural research lab, built
		  specifically to house the models, tests proved that the new design was sound.
		  Construction on the new bridge began in the summer of 1948 and was finished in
		  October 1950. The previous three and a half years spent studying aerodynamics
		  ensured a bridge whose fate would not mimic the first. The Tacoma Narrows
		  Bridge has remained standing.</p></bioghist><bioghist encodinganalog="5450_" id="a2" altrender="sync"><p>Frederick Burt Farquharson was an engineer and professor of
		  engineering. He was born in Boston, Massachusetts in 1895. He studied at the
		  University of Washington, earning his Bachelors of Science in Mechanical
		  Engineering in 1923. He then spent two years working for Boeing Airplane
		  Company, after which he returned to the University of Washington to earn his
		  Masters degree and begin teaching. Farquharson taught in the University of
		  Washington's Department of Civil Engineering. He was granted the status of
		  instructor in 1927, assistant professor in 1928, associate professor in 1937,
		  and professor in 1940. From 1945 to 1963, Professor Farquharson directed the
		  Engineering Experiment Station of the University of Washington. He retired from
		  the University in 1963, and was made professor emeritus that same year. </p><p>Professor Farquharson's professional interests included various
		  aspects of airplane design (especially early in his career), aerodynamics, and
		  the use of wind tunnels for bridge design testing. He is most noted for the use
		  of wind tunnels for his studies of the Tacoma Narrows bridge collapse and for
		  the development of the new Tacoma Narrows bridge. He served on a number of
		  committees concerned with engineering education and research for such
		  professional engineering societies as the American Society of Civil Engineers
		  and the American Society for Engineering Education. Professor Farquharson was
		  also a member of the University of Washington Instructor's Association, which
		  created and assessed a survey of salary and promotion facts, and of faculty
		  opinions regarding the fairness of promotions. He was also called for expert
		  testimony in 1957 in a trial concerning a failed spider staging cable used by a
		  painter at the Weyerhauser Pulp Mill in Cosmopolis, Washington.</p><p>Farquharson was politically active during the economic depression of
		  the 1930's. He had associations with such organizations as the League for
		  Industrial Democracy and the National Council for the Prevention of War. His
		  wife, Mary, was also active in anti-war and civil liberties movements, and
		  served in the Washington State Senate.</p><p>Frederick Burt Farquharson passed away on June 17, 1970.</p></bioghist><scopecontent encodinganalog="5202_" id="a3"><p>The collection consists of images (including prints, negatives,
