Actually, that day came last Friday. From the Philadelpia Inquirer :

Momofuku Ando, 96, the Japanese inventor of instant noodles – a dish that has sustained American college students for decades – has died.

Nissin Food Products Co. said on its Web site that he died Friday in Tokyo after suffering a heart attack.

Born in Taiwan, Mr. Ando founded his company in 1948 from a humble family operation. Faced with food shortages in post-World War II Japan, Ando thought a quality, convenient noodle product would help feed the masses.

In 1958, his Chicken Ramen – the first instant noodle – was introduced after many trials. Following its success, the company added other products, such as the “Cup Noodle” in 1971.

“The Momofuku Ando Instant Ramen Museum” opened in 1999 in Ikeda City in western Japan commemorating his inventions.
