The ASM Headquarters and Geodesic Dome, located in Materials Park, Ohio, is the headquarters of ASM International (formerly the American Society for Metals). Designed by architect John Terence Kelly and completed in 1959, the building is renowned for its striking geodesic dome, which was engineered with the help of Buckminster Fuller’s principles. The open-air dome spans 274 feet and is constructed from aluminum, making it one of the largest of its kind in the world. It serves as a dramatic canopy over the complex and symbolizes innovation in materials science. The headquarters underneath includes offices, meeting spaces, and technical facilities, all reflecting modernist design sensibilities. The dome itself is both a visual landmark and an example of advanced structural engineering. ASM International uses the site for conferences, research, and public education about materials science and engineering. The entire complex is set within landscaped grounds that include a materials-themed garden. In 2009, it was added to the National Register of Historic Places. The ASM Headquarters and Geodesic Dome remain a unique blend of architecture, science, and symbolism.
