Timeline
1920 - 1929
Seattle in 1920 enjoyed a new era of cultural, social, and economic growth never seen in the Pacific Northwest. During this time of promise and excitement, our firm’s founder, William Henry Witt, moved across the country in search of his own American dream and eventually decided to start his engineering practice. The firm we know today as Magnusson Klemencic Associates, an internationally recognized, award-winning engineering company, was born.
1920
W. H. Witt founds company in Seattle, WA
1920-1922
Office Location: Securities Building
1922-1927
Office Location: Seaboard Building
1923
Harold Worthington and George Runciman hired
1927-1960
Office Location: Lloyd Building
1928
Firm formally named the W. H. Witt Company
1930 - 1939
In the 1930s, America, Seattle, and the W. H. Witt Company were hit by the Great Depression, which lasted until 1939 and represented the industrialized world’s worst economic downturn. Companies struggled, banks failed, stores closed, unemployment surged, and engineering projects halted as financing dried up. Washington’s lumber industry crashed without the previous decade’s construction boom. Seattle’s structural engineering and architecture firms closed their doors one by one. Yet, the W. H. Witt Company endured through perseverance, sacrifice, and risk.
1930-1931
Two Seattle projects—the Textile Tower and the Seattle City Light Building—provide the majority of the firm’s income between late 1930 and early 1931
Keeping Afloat
Small steel detailing projects from contractors and fabricators such as Howard S. Wright & Son, Sound Construction and Engineering, Pacific Coast Steel, and West Coast Construction Company (billed for as little as $3 per job) keep the company afloat during the Depression and between larger projects
The New Deal’s infrastructure funding and the Cullen-Harrison Act legalizing beer and wine (ending 13 years of American prohibition) save the company as the firm is hired to build bridges and breweries in Washington
1933
Hailed as America’s longest reinforced concrete span (exclusive of arches), the McMillin Bridge in Pierce County, WA, receives national acclaim in Engineering News-Record
1934
With a central span of 190 feet, the Purdy Bridge in Purdy, WA, is believed at the time to be the longest box girder bridge ever built
1936
The firm designs bottling houses for Rainier Brewing Company in Seattle, WA, and the Olympia Brewing Company in Tumwater, WA
1940 - 1949
Following World War II, the W. H. Witt Company accompanied its architectural clients and expanded its client base into the Alaska Territory to meet postwar demand, resulting in a miniature Klondike Gold Rush. War-era military personnel and construction workers arrived in Alaska by the thousands and decided to stay, creating demand for homes, schools, hospitals, and churches.
In 1945, Harold Worthington and George Runciman quietly celebrated 18 years of partnership under the flag of the W. H. Witt Company.
In November 1945, Worthington and Runciman amicably agreed to separate the firm’s accounts into “Old Witt Co.,” “New Witt Co.,” and “George Runciman.”
1946
Joe Jackson and John Skilling hired
1947
Helge Helle hired
1947
The Loussac-Sogn Building is the largest commercial building in Anchorage, AK, upon completion
1950 - 1959
In the postwar building boom of the 1950s, architects reeled in commissions from developers and owners, resulting in the W. H. Witt Company’s swift uptake of new projects. Buildings were constructed more economically by contractors who respected Worthington & Skilling’s efficient structural designs. After enjoying their experience and being impressed with the innovation, architects and owners returned for more. The firm added the innovative minds of many talented individuals this decade, including Jack Christiansen, Bill Ward, Kent Rogers, and Les Robertson, and added a Civil Engineering practice.

1954
Bill Ward hired
1955

1958
Les Robertson hired
1960 - 1969
The dawn of the 1960s revealed space exploration, scientific advancements, and political energy unlike any decade prior. The Space Race captivated the world, evidenced by the many attractions underway at the Century 21 Exposition / Seattle World’s Fair. The engineering world also reached new heights as Worthington, Skilling, Helle & Jackson was commissioned to design the world’s tallest buildings—the World Trade Center towers in New York City.
1960
Firm name changes to Worthington, Skilling, Helle & Jackson

1970 - 1979
As many Americans continued to fight for expanded social and political rights, the country also saw a shift away from politics and turn toward pop culture. In the engineering world, the success of NASA’s space program encouraged many young people to pursue careers in STEM from the late 60s through the 70s. However, the country’s recession from 1973 to 1975 ended the postwar boom enjoyed for the last several decades, and the oil crisis of this period shifted the nation’s priorities toward energy and conservation. Jack Christiansen’s beautiful thin-shelled roofs began to fade out, and in came the era of steel domination and its economic viability, given international competition and trade globalization.
1972
New York City’s World Trade Center Towers are the world’s tallest buildings at the time of completion and the first to use prefabricated, multiple-column-and-spandrel steel wall panels and mechanical damping units to reduce wind “excitation”; it also is the first project to perform comprehensive studies surrounding wind environments and human sensitivity to building motions, as well as boundary layers utilizing wind tunnel testing

1980 - 1989
Beyond political tensions of the ongoing Cold War, increasing popularity of “Reaganomics,” and the age of entertainment, one of the most significant shifts of the time was the personal computer. As Apple launched its Macintosh and Silicon Valley became the hub of technological advancement, the engineering world saw ever-increasing opportunities. Programs like FORTRAN allowed Skilling to employ the benefits of computer-optimized designs on innovative projects like Columbia Center and Century Square in downtown Seattle.

Two Union Square in Seattle, WA, is the first building to use steel pipes filled with a world-record-breaking, high-strength, 19,000-psi concrete and hyper-efficient, viscoelastic dampers
1990 - 1999
Building on the previous decade’s success, cost savings, and innovations, SWMB had a solidified reputation as one of the most prominent engineering firms entering the 1990s. A decade remembered as both comfortable and transformative, technology and the growing power of the internet changed everything from politics and domestic life to business and the economy. With an ever-expanding project portfolio, the firm capitalized on its “Market Sector” approach to diversify pursuits and expand the talent pool of experts in particular building types.
