Дональд Глазер: Физик, нейробиолог және Нобель сыйлығының лауреаты

American physicist and neurobiologist

Donald Arthur Glaser (September 21, 1926 – February 28, 2013) was an American physicist, neurobiologist, and the winner of the 1960 Nobel Prize in Physics for his invention of the bubble chamber used in subatomic particle physics.

Born in Cleveland, Ohio, Glaser completed his Bachelor of Science degree in physics and mathematics from Case School of Applied Science Glaser accepted a position as an instructor at the University of Michigan in 1949, and was promoted to professor in 1957. He joined the faculty of the University of California at Berkeley, in 1959, as a professor of physics. During this time his research concerned short lived elementary particles. The bubble chamber enabled him to observe the paths and lifetimes of the particles. Starting in 1962, Glaser changed his field of research to molecular biology, starting with a project on ultraviolet induced cancer. In 1964, he was given the additional title of professor of molecular biology. Glaser's position (since 1989) was professor of physics and neurobiology in the graduate school.

Donald Glaser was born on September 21, 1926, in Cleveland, Ohio, to Russian Jewish immigrants, Lena and William J. Glaser, a businessman. He enjoyed music and played the piano, violin, and viola. He went to Cleveland Heights High School, where he became interested in physics as a means to understand the physical world.

After winning the Nobel Prize, Glaser began to think about switching from physics into a new field. He wanted to concentrate on science, and found that as the experiments and equipment grew larger in scale and cost, he was doing more administrative work. He also anticipated that the ever more complex equipment would cause consolidation into fewer sites and would require more travel for physicists working in high energy physics. Recalling his interest in molecular genetics that began at Caltech, Glaser began to study biology. He spent a semester at MIT as a visiting professor and attended biology seminars there, and also spent a semester at Copenhagen with Ole Maaloe, the prominent Danish molecular biologist. Glazer told his business colleagues at Cetus that after winning the Nobel prize he decided he had spent the first part of his life studying the physical world and that he now wanted to study the basis of life itself so he changed to studying biology and genetics. He made the comment “As a physicist and highly trained engineer my immediate thought upon entering my first biology lab was that Louis Pasteur would be comfortable working there.” He then went on to develop equipment to automate various biological processes. In fact, Cetus was originally formed to utilize his inventions and expertise with its first projects focused on producing higher yielding antibiotic strains as the company then evolved, pioneering the field of biotechnology. He worked in UC Berkeley's Virus Lab (now the Biochemistry and Virus Laboratory), doing experiments with bacterial phages, bacteria, and mammalian cells. He studied the development of cancer cells, in particular the skin cancer xeroderma pigmentosum. As with the bubble chamber, he used his experience designing equipment to improve the experimental process. He automated the process of pouring out agar, spreading culture, and counting colonies of cells using a machine he called the dumbwaiter. It took photographs, administered chemicals, and had a mechanical hand to pick up colonies.

While continuing to work at UC Berkeley, Glaser started Berkeley Scientific Laboratory with Bill Wattenberg in 1968. The short lived partnership worked on automating diagnostic procedures. In 1971 he founded Cetus Corporation with Moshe Alafi, Ron Cape, and Peter Farley. Glaser's position was chairman of the science advisory board. The founders felt that the knowledge scientists had gained about DNA had not yet been applied to solve real problems. The company did microbial strain improvement, and then genetic engineering, becoming the first biotechnology company. Cetus was purchased by Chiron Corporation in 1991.

As molecular biology became more dependent on biochemistry, Glaser again considered a career change. His experience automating visual tasks in physics and molecular biology led him to an interest in human vision and how the brain processes what is seen. He began to work on computational modeling of the visual system and visual psychophysics, and spent a sabbatical at the Rowland Institute for Science.
