Koichi Tanaka (田中 耕一 Tanaka Kōichi, born August 3, 1959) is a Japanese scientist who won the macromolecules.[1]

Tanaka was born and raised in Toyama, Japan. In 1983, he graduated from Tohoku University with a bachelor's degree in engineering. As of 2006, he is the only person without a post-bachelor's degree to have won a Nobel Prize in a scientific field. After graduation, he joined Shimadzu Corporation, where he engaged in the development of mass spectrometers.

For mass spectrometry analyses of a macromolecule, such as a soft laser desorption (SLD).[2]

However, there was some criticism about his winning the prize, saying that contribution by two German scientists, Franz Hillenkamp and Michael Karas was also big enough not to be dismissed, and therefore they should also be included as prize winners. This is because they first reported in 1985 a method, with higher sensitivity using a small proteins until after Tanaka's report.[4]
