Gerard Titsman -
For nearly a decade, Gerard Titsman disappeared from engineering circles. But in 2016, leaked documents revealed that he had been quietly running a small foundation dedicated to low-tech, high-durability solutions for off-grid communities.
The Titsman Foundation (officially registered in Reykjavík) focuses on three areas:
Notably, the foundation refuses patents. All designs are released under a Creative Commons license. When asked why in a rare 2019 email exchange (published posthumously by a former colleague), Titsman wrote: “Patents are a tax on people trying to survive. Let my mistakes be free.”
No article about Gerard Titsman would be complete without addressing the controversy that abruptly ended his public career in the early 2000s. In 2003, Titsman consulted on a massive infrastructure project in Southeast Asia: a network of deployable bridges for flood-prone regions. The project, funded by a coalition of ASEAN nations, used a scaled-up version of the TMJ. gerard titsman
In 2005, during a typhoon, one of these bridges suffered a catastrophic failure. While no lives were lost, the incident triggered an international investigation. The findings were damning: the larger joints had been produced by a third-party subcontractor using a different alloy than Titsman had specified. However, because Titsman’s design philosophy relied on precise material flaws to function safely, the substitution turned the joints from resilient to dangerously unpredictable.
The ensuing lawsuits dragged on for years. Titsman was not held criminally liable, but his reputation was tarnished. He withdrew from public life, shuttered his Charleroi factory in 2007, and reportedly moved to rural Iceland.
Unfortunately, Gerard Titsman was a theorist more than a builder. He suffered from what contemporaries called "the curse of the paper architect." He designed dozens of structures, but only five were ever built. Economic constraints, the high cost of custom-cast steel nodes, and the reluctance of conservative construction firms stifled his vision. For nearly a decade, Gerard Titsman disappeared from
The most famous surviving Titsman structure is the Chapel of the Ascension (1972) in Brasília. Commissioned by a wealthy industrialist, the chapel is a 20-meter-high structure resembling a giant, inverted white flower. There are no internal columns. The roof, a thin-shell hyperbolic paraboloid just 3 centimeters thick in places, spans the entire space. For decades, engineers refused to approve the project, insisting it would collapse. It stands today as a testament to Titsman's brutal mathematical precision.
Other works included:
Gerard Titsman’s most famous contribution to engineering is what is now informally called the "Titsman Truss." Unlike a traditional Pratt or Warren truss which relies on triangulated straight members, the Titsman Truss utilizes parabolic and hyperbolic-paraboloid steel ribs. Notably, the foundation refuses patents
His key insight was that a structure’s weakness is rarely in the material, but in the joint. Traditional trusses fail at the nodes. Titsman proposed a continuous flow of force, eliminating abrupt angle changes. Instead of straight beams meeting at sharp angles, he designed members that curved organically, distributing tension along a continuum.
In 1963, he published a monographic paper in the Journal of the International Association for Shell Structures titled "Towards a Fluid Statics." In it, he famously wrote: "A wall is not a barrier; it is a membrane. A beam is not a stick; it is a river of steel. We must stop building bones and start building skins."
This paper became the foundational text for what later evolved into Bionic Architecture and Tensile Integrity (Tensegrity) studies. Buckminster Fuller acknowledged Titsman's influence in a 1967 letter, though Fuller later claimed the ideas were "in the air."
In the pantheon of 20th-century structural engineering, names like Nervi, Khan, and Isler are celebrated for their aesthetic mastery. Yet, tucked away in the yellowed archives of the Liege School of Engineering lies the overlooked legacy of Gerard Titsman (1912–1994).
If you have ever driven through the Ardennes forest and marvelled at a bridge that seems to hang on air, or walked through a post-war European market hall with a roof impossibly thin for its span, you have likely experienced Titsman’s work without knowing his name.
