Lella Vignelli, a designer who, with her husband, Massimo Vignelli, introduced a spare, elegant style to a wide range of products and corporate brands, attracting an international clientele, died on Dec. 22 at her home in Manhattan. She was 82.
The cause was dementia, her son, Luca, said.
Ms. Vignelli, an architect by training, brought a three-dimensional imagination to her husband’s graphic-design sensibility. Together, they were a two-person design army with a shared aesthetic — sleek and intelligent — that appealed to clients eager to express a new identity or to develop products with bold, modernist lines.
After working with Italian companies like Pirelli and Olivetti in the early 1960s, the Vignellis established an American base of operations through Unimark, their corporate branding company, and, later, Vignelli Associates, which they founded in 1971, and a sister company, Vignelli Designs, which began in 1978.
