Jean Baptiste Andre Dumas was a French chemist in the 19th century, following the time of Marggraf, living from 1800-1884. He completed very influential work in the area of atomic masses as he adjusted values for more than 30 elements, including establishing the mass of Hydrogen as 1. But, as it pertains to the understanding of glucose Dumas was responsible solely for the name. Remember, Marggraf had only referred to the "white powder" as some type of sugar, but did not designate it a name. Dumas chose "glucose" from the Greek word "glycos," meaning "sweet." In fact, the sweetness of the compound was the lone characteristic people had observed and cared for to that point in history. They did not realize the incredible importance of the molecule and the research done, had not even approached the vast realm of its uses. The suffix -ose implies the molecule is a sugar, and is the way in biochemistry of identifying such.
