The life of Ira Remsen Ira Remsen was born on February 10, 1846 in New York city. Even though he was born in the United States, he was educated in Germany. He received his M. D. at Columbia University in 1867 and he also earned a Ph.
D. at the University of Munich and Gtt ingen in Germany. After receiving his degrees, Remsen began his investigation in pure chemistry at the University of T bingen. It was in Germany and in Europe Remsen did most of his research. In 1876 he returned to the United States where his became one of the original faculty of Johns Hopkins University. There he founded the chemistry department.
He was an excellent professor who trained a generation of prominent chemists. He was also the Director of the chemical laboratory and secretary of the Academic Council. In 1879, he was the founding editor of American Chemical Journal. Also in that same year, he made a remarkable, accidental discovery with a fellow researcher Constantine Fahlberg when they were working on a derivative of coal tar. One night, after a long day in his laboratory He we was having dinner with wife. When he was eating a regular roll.
Remsen noticed that it was quite sweet at first, but it left a bitter after-taste. He made his wife taste the bread and he found nothing wrong or something unusual about the taste. So Remsen decided to taste his fingers and there he found that same sweet then bitter taste despite washing his hands thoroughly after working in his lab. After dinner, he returned to his laboratory and started to taste all the chemicals he was handling. When he found that chemical, it was oxidation of o-toluene sulfonamide and he called it saccharin. In 1880, Remsen and Fahlberg published their findings in the February issue of The Chemical Journal.

Many people thought that it was Constantine who discovered saccharin, but he stole the formula from Remsen. When they stopped working together Constantine patented the formula and became filthy rich. As a result Remsen didn’t received any credit for the discovery. Constantine received the recognition that Remsen earned and rightfully deserved. Remsen was furious at first about the matter; “it makes my blood boil to see the lies that scoundrel Fahlberg constantly, constantly in print, and to see further, that they are generally believed.” Later Remsen would apologize for this outburst. Remsen moved to bigger and better things.
In 1901, he was appointed President of Johns Hopkins University, there in that same year, he wrote several important textbooks on chemistry. Remsen also found the School of Engineering at Johns Hopkins. He introduced many German laboratory methods into Johns Hopkins and emphasized the university’s function as a research “centre.” At the time at Johns Hopkins he helped establish the school as a leading graduate science teaching institute in the United States, never seeking fame or fortune for his contributions to science. His work on the research-based Doctoral program at Hopkins was considered important improvement to science in the United States.
In 1913, Dr. Ira Remsen stepped down as president at Johns Hopkins University. Remsen still continued to keep chemistry the number one priority in his life. He moved and resided in Carmel, California. Until his passing away on March 4, 1927 of natural causes.
Saccharin Saccharin is derived from the Latin word sacc harum, meaning sugar. Saccharin is also called Ortho-sulfobenzoic acid imide; the formula is C 6 H 4 CONHSO 2. Saccharin is a synthetic, white, crystalline powder that melts at 228. 08 to 229. 7 degrees Celsius and very soluble in water. It is 550 times as sweet as sugar cane.
The Essay on John Charles Fields Mathematics Institute Medal
John Charles Fields John Charles Fields is perhaps one of the most famous Canadian Mathematicians of all time. He was born on May 14, 1863 in Hamilton Ontario, and died August 9, 1932 in Toronto, Ontario (Young, 1998). He graduated from the University of Toronto at the age of 21 with a B. A in Mathematics and went on to get his Ph. D. at John Hopkins University in 1887. Fields was very interested ...
And it is also estimated to have a sweetening power 375 times that of sugar. When saccharin is dissolved in water in large amounts, the solution is very bitter. Sweetness is only evident in a diluted solution. Saccharin cannot be digested by the body and has no food values. Those who are diabetic and people who ate on weight reducing diets use it in place of sugar. They used it for the psychological purpose of satisfying a taste for sweetness.
Many critics say that that saccharin can itself stimulate the appetite and the production of insulin in the body. For several years, saccharin has been under investigation as a risk for cancer. It was banned in Canada in 1977 for that same reason. But in the United States Public reaction has help to keep saccharin on the market. The Food and Drug Administration requires that warning labels to be put on products containing saccharin.
