...long time, they said, researchers have known that cancer cells consume an abnormally small amount of oxygen. To find out why, Drs. Davis and Schmitz probed an enormous rat tumor, discovered small pockets of poisonous cyanogen gas along its borders. They also confirmed the presence of cyanogen along the edges of a human tumor. Cyanogen gas, in minute amounts, is a normal cellular waste product, ordinarily passed out into the blood stream through porous cell walls...
Schleiden and Schwann. In 1839 in Germany lived two scientists, Mathias Schleiden and his follower, Theodore Schwann. In his publication on the cell issued at that time, Schleiden made this statement: "Each cell leads a double life: an independent one pertaining to its own development alone, and another, incidental insofar as it has become an integral part of the plant. It is, however, apparent that the vital process of the individual cell must form the very first, absolutely indispensable basis of ... physiology...
Many a textbook since then has honored Schleiden and Schwann as the first to postulate that the cell is a fundamental unit of life. Some time ago Joseph Meyer, a consultant at the Library of Congress, conceived the idea of a great centenary celebration in honor of Schleiden and Schwann and of the discovery of the cell theory in 1839. Hence Stanford's symposium...
There is nothing that Biologist Conklin wants less than to spoil the celebration. But as a scholar and scientist he is an uncompromising iconoclast. So he thinks it only fair to make the point that the cell theory was set afoot not in 1839 but during the previous 170 years, not by Herren Schleiden and Schwann but by a number of men almost nobody knows...
...able, mechanically talented scientist who suffered the misfortune to be a 17th-Century contemporary of the great Isaac ("Falling Apple") Newton. He was embittered by having to live in the shadow of Newton's greater glory. But frustrated Robert Hooke saw, named, described and pictured living cells, and he appears to have been the first to do so. Thereafter numbers of other scientists saw and studied cells.** For a long time the mysterious little chambers of life were called by various names, such as "vesicles," "utricles" and "globules." Then Hooke's original name, "cell," came back into...
