...first business day of 1931, Harvey Dow Gibson, then chairman of the executive committee of New York Trust Co., and a group of wealthy friends bought control of Manufacturers Trust Co. from Goldman Sachs Trading Corp. They paid $7,300,000. The deal brought an end to much gloomy talk about Manufacturers Trust after its proposed merger with Bank of United States had fallen through (TIME, Jan. 12). When J. P. Morgan one afternoon walked out of his little grey banking house at No. 23 Wall Street and dropped in to see Mr. Gibson in his new office...
...determined. But the only method of studying the effects of centrifugal force was to whirl cells in a tube, then remove them and see what had happened. Alfred Lee Loomis, a New York banker (Bonbright & Co.) who has a private laboratory at Tuxedo Park, and Dr. Edmund Newton Harvey of Princeton University devised a microscope through which cells could be studied as they whirled. Last week they made experiments with this device, which they call...
...rotated at the rate of 8.000 revolutions a minute, and the whirling cell at one end of the bar can be seen through the stationary eyepiece over its centre. But the image thus presented was blurred, since it was seen in motion as it passed the light. Scientists Loomis & Harvey fixed the light so that it would flash on and off, each Hash coinciding with the reappearance of the cell beneath the lamp. Thus a series of distinct, clear pictures was presented-8,000 of them to the minute, so many that the eye could not detect the periods...
Scientists Harvey & Loomis watched cells whirl, saw the tiny granules moving through the protoplasm, oil globules going in one direction, yolk granules in another. From the rate of movement they began to calculate the viscosity (gumminess) of the protoplasm. When oil and yolk are separated they exert a pull upon the cell which divides it in two parts. By watching the course of that process the experimenters were able to estimate the tension on the surface of the cell which holds it together. That tension, they found, is at least 100 times smaller than had been supposed. Preliminary results...
Biologist Harvey and Banker Loomis are old collaborators. Two years ago they devised a chronograph to record the speed and variation of human heart beats over long periods. They have developed an ultra-rapid micro-cinema camera which photographs the "death" of cells when attacked by intense sound waves. In his Tuxedo Park laboratory Mr. Loomis has experimented for years with "super sound" waves, too rapid for the human ear to detect, which kill fish, paralyze mice, sterilize blood (TIME, Feb. 6, 1928). But electricity and physics are only a pastime with him. In 1920, with Landon K. Thome...
