Birth of George Bergstrom, Architect of the Pentagon
March 12, 1876 Birth of George Bergstrom, Architect of the Pentagon
George Bergstrom was born on March 12, 1876, and would go on to design one of America's most recognizable structures — the Pentagon. He built his reputation on the West Coast before Secretary of War Henry L. Stimson named him chief consulting architect in February 1941. He helped shape the Pentagon's iconic five-sided layout in just six days. His story, though, takes a dramatic turn you won't want to miss.

George Bergstrom: The Architect Who Designed America's Largest Office Building
George Edwin Bergstrom, born March 12, 1876, built his reputation as one of the West Coast's premier architects before taking on the project that would define his legacy: the Pentagon. His architect biography reads like a masterclass in versatility — designing the Pasadena Civic Auditorium, the Los Angeles Athletic Club, and Grauman's Metropolitan Theater shaped his design philosophy around large-scale, functional structures.
When the U.S. Army appointed him chief architect in July 1941, you can see how his expertise in reinforced concrete construction made him the right choice. Within just five days — July 17-22 — he'd co-designed the Pentagon's basic layout with David J. Witmer. Ground broke September 11, 1941, producing the world's largest office building by January 1943.
How Bergstrom Left New York to Dominate West Coast Architecture
Before Bergstrom's name became synonymous with West Coast architecture, he'd cut his teeth in New York, working as a project supervisor at Tower and Wallace, Architects from 1901 to 1903. There, he gained essential expertise in reinforced concrete construction—a skill that would define his career.
His move west wasn't just relocation; it was a reinvention strategy. You can see it in the results: he rose to become Los Angeles' premier architect, designing landmark projects like the Pasadena Civic Auditorium, the Los Angeles Athletic Club, and Grauman's Metropolitan Theater and Office Building in 1923. He didn't simply transplant his New York experience—he leveraged it, using his concrete construction knowledge to establish dominance in a rapidly growing California market hungry for ambitious, modern buildings. This same spirit of calculated reinvention echoed decades later in Silicon Valley, where Bill Hewlett and Dave Packard transformed a 12x18-foot Palo Alto garage and just $538 in startup capital into what would become one of the world's most influential technology companies.
The Los Angeles Buildings That Made Bergstrom Famous
Bergstrom's West Coast ambitions crystallized into three buildings that cemented his reputation in Los Angeles: the Pasadena Civic Auditorium, the Los Angeles Athletic Club, and Grauman's Metropolitan Theater and Office Building, completed in 1923. Each project demonstrated his command of scale, materials, and civic purpose.
The Pasadena Civic Auditorium stands as perhaps his most enduring local legacy. Its Neoclassical Revival design communicates authority and permanence, qualities that defined Bergstrom's architectural voice throughout his California career. You can see in these buildings a consistent ambition: he wasn't simply filling commissions; he was shaping how Los Angeles presented itself to the world. By the time Grauman's Metropolitan opened, Bergstrom had firmly established himself as the region's most consequential architect, positioning him for even larger national opportunities ahead.
How Did Bergstrom Win the Pentagon Commission?
The Pentagon commission didn't come through a traditional competitive bid — it landed in Bergstrom's hands through a direct appointment. Secretary of War Henry L. Stimson named him chief consulting architect in February 1941, a move that reflected both political patronage and wartime urgency. Stimson's office needed someone proven, well-connected, and capable of executing an unprecedented federal project without delay.
Bergstrom's AIA presidency gave him exactly the visibility that mattered. When you're leading the nation's most prominent architectural organization through 1939 and 1941, military officials notice. By July 1941, the Army assigned him as chief architect. Within days, he and David J. Witmer had sketched the building's basic five-sided layout.
Ground broke on September 11, 1941 — speed that only wartime urgency could demand. Similar to how Canada's Bill C-49 sought to modify the legal framework for Atlantic offshore energy resources, large-scale government initiatives often require purpose-built legislation and appointed experts to navigate unprecedented regulatory and construction challenges.
How Bergstrom Designed the Pentagon in Six Days
Once Bergstrom had the commission, he moved fast. Between July 17 and 22, 1941, he and David J. Witmer completed the Pentagon's basic layout in just six days. That's rapid sketching at its most intense—translating military requirements into a coherent five-sided reinforced concrete structure within less than a week.
You'd notice how material optimization shaped every decision. Bergstrom drew on his expertise in reinforced concrete construction, the same knowledge he'd built during his early career in New York. Steel was scarce, so concrete became the logical solution. The five-sided shape itself wasn't arbitrary—it fit the original site's geometry while minimizing corridor distances.
Ground broke on September 11, 1941, confirming that Bergstrom's rapid design process had produced something the Army could actually build. Similarly, large-scale recovery operations often depend on assessment technology and GIS integration to translate complex logistical requirements into actionable plans under tight timelines.
How Bergstrom's Design Made the Pentagon's Construction Possible
Rapid design only matters if builders can execute it, and Bergstrom's layout gave them exactly what they needed. His structural innovation — a reinforced concrete framework — eliminated reliance on steel, a material the military couldn't spare during wartime. That single decision kept construction logistics moving without competing against weapon and vehicle production.
You'd also notice how the five-ring, concentric layout allowed crews to build in phases. Workers didn't wait for one section to finish before starting another. Instead, different rings went up simultaneously, compressing a project of this scale into roughly 16 months. Ground broke on September 11, 1941, and the structure was complete by January 15, 1943. Bergstrom's design didn't just look workable on paper — it proved workable in practice, under real wartime pressure. This kind of engineering ingenuity under constraint echoes the work of earlier industrial pioneers, such as George Stephenson, who solved the problem of crossing the boggy Chat Moss terrain during railway construction by developing a floating raft foundation.
From AIA President to Disgrace: Bergstrom's Removal as Pentagon Architect
Bergstrom's fall from professional grace came swiftly. Just months after breaking ground on the Pentagon, charges of improper conduct surfaced against him. The ethical lapse that ended his tenure remains vague in historical records, but its consequences were immediate and severe.
You can trace the professional fallout directly to April 1942, when Bergstrom resigned his position as the Army's chief Pentagon architect. David J. Witmer, who'd helped Bergstrom design the Pentagon's basic layout just months earlier, stepped in as his replacement on April 11, 1942.
The disgrace hit harder given his stature. Bergstrom had served as AIA President from 1939 to 1941, making him one of American architecture's most prominent figures before his rapid, humiliating exit from the project he'd conceived.
Bergstrom's Quiet Years After the Pentagon
After his resignation, Bergstrom largely faded from public view. You won't find headlines celebrating his postwar travels or major professional milestones. He spent time in Brazil in 1943 before eventually returning to the West Coast, settling in Claremont, California, during the 1950s. His days of designing landmark civic structures and leading the AIA were behind him.
He likely took on private commissions during these quieter years, though none matched the scale or visibility of the Pentagon. The disgrace surrounding his 1942 removal had effectively closed doors that his earlier prominence had opened. He died on June 17, 1955, survived by his wife Alice C. Lytle, his son George Jr., and his brother James — a quiet end for the man who'd designed America's most iconic military building.
