Lella Vignelli, an architect by training and largely regarded as the three-dimensional expert in the work she did with her graphic designer husband Massimo Vingelli, passed in her Manhattan home on Dec. 22. According to The New York Times report, the cause was dementia.

The design duo, who met at an architecture convention, is responsible for major design projects such as the double-A logo for American Airlines, Bloomingdale's brown paper bags, and the transportation graphics for both the New York Metropolitan Transit Authority and Washington Metro Transportation through their consulting firm Unimark. However, to the couple's dismay, Massimo was usually the only figure credited for their work by architecture and design critics.

To be closer, both of the designers enrolled at the University of Venice School of Architecture, and later married in 1957 when Massimo accepted a design job in the U.S. During this time, Ms. Vignelli was accepted as a "special student" at M.I.T.'s School of Architecture and Planning, and later worked as a junior interior designer for Skidmore, Owings & Merill in Chicago. After returning to Italy, she opened a design and architecture office with Massimo, and later completed her architecture degree at the University of Venice in 1962.
