Tizio lamp for Artemide, one of the first desk lamps using halogen bulbs with low-voltage current conducting arms to eliminate the need for wires. The Tizio remains one of the best selling lamps ever produced. Sapper continued to create design classics including the Sapper Office Chair series for Knoll in 1979, a series of stop watches for Heuer in 1976 and the Nena folding chair for B&B Italia in 1984. In 1978 Alessi commissioned Sapper with the first product in a long series to come, the stove-top espresso maker 9090. It was followed, amongst other products, by the two-note whistling water kettle Bollitore in 1984, the Bandung teapot in 1990, the Coban espresso machine in 1997, the cheese grater Todo in 2006 and the Cintura di orione cookware series in 1986 and 2009, conceived with the collaboration of renowned chefs such as Roger Verge, Pierre and Michel Troisgros, and Alain Chapel.
In 1980 Sapper was appointed principal industrial design consultant at IBM and began designing numerous portable computers, including the first ThinkPad 700C in 1992, which broke with the company's tradition of pearl-grey machines as a simple and elegant black rectangular box that would reveal a surprise inside: a small red button amidst the keyboard which would serve to control the screen cursor. Sapper continues today to oversee the iconic ThinkPad brand as design consultant to Lenovo after it acquired the IBM PC Division in May 2005.
