Biographical NoteReturn to Top

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.

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.

Farquharson was politically active during the economic depression of the 1930s. 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.

Frederick Burt Farquharson passed away on June 17, 1970.

Historical BackgroundReturn to Top

Construction began on the original Tacoma Narrows Bridge in November 1938. On July 1, 1940, the bridge opened to traffic. Lauded as an essential economic and military portal to the Olympic peninsula, its completion was called a triumph of man's ingenuity and perseverance. It had been completed in record time and, with a 2,800-foot central span, was the third largest span in the world. Immediately upon its opening it began swaying in the wind, which earned it the nickname “Galloping Gertie.” Only four months later, the bridge collapsed on November 7, 1940, in winds of 42 mph (67 km/h). This collapse was deemed “the Pearl Harbor of engineering."

Contemporary accounts appeared to be shocked by the collapse, although the bridge had begun exhibiting wavelike motions during the final stages of construction. 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.

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. Farquharson claimed that the bridge “had a lateral twisting motion, in addition to the vertical wave,” which the bridge hadn’t exhibited before. The first span of the bridge to give way did so around 11:02 AM. This began with a 600-foot section towards the west side of the bridge; following this, another span dropped. By 11:10 AM the bridge had settled with a 30 foot deep sag to it.

Farquharson wasn’t the only man with a movie camera that day. He was accompanied on the east side of the bridge by two attendants from Tacoma’s The Camera Shop, Barney Elliot and Harbine Monroe, and by Walter Miles, a supervisor with the Pacific Bridge Company. On the west side of the bridge was Dr. Jesse Read whose footage has disappeared.

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. The only fatality was a family dog, Tubby, who was too afraid to exit the car in which he was seated.

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.

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.

Content DescriptionReturn to Top

The Tacoma Narrows Bridge film collection consists of footage of the construction, failure, collapse and aftermath of the Tacoma Narrows Bridge, including newsreels, on-site and laboratory testing, and films of the second Tacoma Narrows Bridge. Films were created by Frederick B. Farquharson, head of the University of Washington Engineering Experiment Station, Phil Jacobaea from the University of Washington Campus Studios, as well as Barney Elliot and Harbine Monroe of the Tacoma Camera Shop. Films from the University of Washington Engineering Experiment Station, the University of Washington Audio Visual Services Materials Library, and the University of Washington Educational Media Center were brought together to form this collection.

Negative Cuttings Tacoma
A montage of clips from before, during, and after the collapse, with no clear order assigned. The 1/100 scale model in the University of Washington Structural Laboratory oscillates. The Tacoma Narrows Bridge oscillates pre-failure. The bridge oscillates aggressively on its day of failure. People survey the damage. Professor Farquharson observes the entire bridge with a collapsed mid-section. People and cars cross the mildly oscillating bridge before it fails. The camera surveys the remains of the collapsed bridge. A man walks off of the wildly oscillating bridge on the day of collapse. The roadway breaks.

A group of people walk across the partially constructed 1950 bridge. The group pose in front of one of the main cables. Workers tie metal cables to secure the "cable band" around the wires that make up the main cable. The camera examines the warren truss of the bridge from below. Cars drive across the bridge with Mt. Rainier in the background. The bridge is filmed from the perspective of those driving over it. A worker attached to one of the main cables waves to the camera. Cars pass through the toll station. Two men converse. A procession of cars crosses the bridge to celebrate its opening.

Cable Spinning
The 1950 Tacoma Narrows Bridge is opened with a speech and crowds celebrating. A team of people involved in the project pose in front of a main cable during construction. A painted model demonstrates how wires are carried across the span. Reels of wires are processed on site during construction. Wires are moved across the bridge by a spinning wheel on a pilot line. Workers tie the wires together to make the cable. Workers on a catwalk tie metal cables to secure the "cable band" around the wires that make up the main cable. The cables are painted orange. The bridge is operational with Mt Rainier in the background.
