Until Coulter Corporation was sold to Beckman Instruments in late 1997. Organization in 1976, where in June 1978 I became his technical advisor, a position I held That discussion led him to have me recruited into the Coulter University, which prompted a call from Wallace H. Led to purchase of a Coulter Counter® Model ZB during my Ph.D. Its sensingĪperture puzzled me, and I began searching library stacks for explanations. Model A exhibited by the Biology Department and was allowed to operate it. Which I attended as a graduating high-school senior.

Number of casualties from the Hiroshima and Nagasaki bombings. On the Coulter Principle daily process blood samples from many more patients than the The Coulter Principle states that if a suspension of blood cells is passed throughĪ small restriction simultaneously with an electric current, the cells will modulate theĬurrent, so enabling them to be counted and sized. Period here considered these are summarized as context for his developmental activities. Increasingly powerful nuclear weapons were important motivations for him throughout the International cold-war politics and the burgeoning of Sophisticated instrumentation for analysis not only of blood cells, but of particles involved The Coulter Principle, its commercialization in the first widely available automated bloodcellĬounter, and elaboration of that ground-breaking counter into increasingly Story of his journey from that comprehension through his invention and implementation of In providing care for victims of radiation exposure. ![]() Coulter abruptly comprehend the critical need for rapid and accurate blood-cell counts The atomic bombings of Hiroshima and Nagasaki in August 1945 made Wallace The Coulter Principle: For the Good of Humankind The Long Pendency of DuPage County Case 1-61-141 Characteristics of Coulter Sensing Apertures Apparatus from ONR Contract NONR-1054 (00) Proposal to Office of Naval Research (ONR) Proposal to Argonne National Laboratory (ANL) Method of Counting Small Particles (August 1948) Method of Counting Small Particles (July 26, 1948) Photo-electric Method of Counting Small Particles
