Architects Claus Bonderup and Torsten Thorup were students at the Royal Danish Academy of Fine Arts when they co-designed their first lamp. Craving pure, crisp geometric shapes in a design world dominated by soft organic forms, they created the Semi Pendant (1968) by placing two circles back to back, producing an elegant shape in the negative space between with a diameter matching that of each circle. Timeless by design, â€œit just has that simplicity of form, which cannot be slotted into any single style period,â€ says Bonderup. Itâ€™s not surprising that Semi took first prize in the School of Architectureâ€™s 1968 design competition with its satisfying, perfectly balanced proportions.
