...chlorophyll craze which has been sweeping the U.S. for two years or more has no justification in scientific fact, the American Chemical Society heard last week from a topflight chemist, Professor Alsoph H. Corwin of Johns Hopkins...
...first place, said Chemist Corwin, little is known about the action of true chlorophyll in the human body, and most of the technical literature on the subject is full of myths. Anyhow, the material used by manufacturers of green pills, chewing gum, toothpaste and mouthwash is not natural chlorophyll: it has been altered chemically and sometimes contains copper. Much of it is labeled "copper chlorophyllin," and even this is a misnomer, said Corwin, because a "phyllin" is a magnesium derivative; when copper replaces the magnesium, it's something else again...
...Chlorophyll," said Chemist Corwin in summation, "is indispensable to photosynthesis. It is highly esthetic in coloring the vistas visible from hills or mountains. It furnishes chemists, physiologists and other scientists with a lot of good, clean fun. For other purposes, we are not certain that it has any value...
...Harvard men and a University of Chicago professor speak on the question. "Is the concept of Science different in Biology from what it is in the Physical Sciences?" In this symposium, the first meeting of the Boston Society of Biologists held at M.I.T., President Conant spoke for the chemist, Dr. Philipp G. Frank, lecturer on Physics and Mathematics, represented his fields and Dr. Paul Weiss, professor of Zoology at the University of Chicago, took the biologist's viewpoint...
Very few university presidents are as active in as many areas as is President Conant. He was an outstanding organic chemist, became a respected leader in education and has recently asserted himself as an interpreter of the development of science. With the publication of his Bampton lectures given at Columbia last Spring, Conant emerges as a sociologist and philosopher of science...
