On 05.27.14, just a few weeks after Massimo Vignelli’s son invited designers who were influenced by the graphic designer to send him a letter of support and gratitude, Vignelli passed away at the age of 83. The design world, and our city, is deeply indebted to the work of the Italian-born, NYC-based designer. Vignelli’s famed 1972 subway map of New York City still lives on the MTA’s The Weekender website. His design for NYC’s subway system signage has been extended to other elements of the city, including the city’s website and pedestrian way-finding maps. So this week, as you ride the subway, take a minute to think about, and thank, Massimo Vignelli.
