Biography
Walter Houser Brattain (1902–1987) was an American physicist born in Xiamen, China. He was one of the co-inventors of the transistor and won the Nobel Prize in Physics in 1956. Although born in China, Brattain grew up and was educated in the United States, attending Queen Anne High School and Tonasket High School. He went on to study at Whitman College, the University of Oregon, and earned his doctorate at the University of Minnesota. His time at the University of Oregon College of Arts and Sciences gave him a broad scientific background that was crucial to his later work in solid-state physics.
Brattain's major scientific achievement came when he worked with John Bardeen and William Shockley at Bell Telephone Laboratories, where they developed the transistor in 1947. This invention changed electronics and started the modern computer era. The transistor was a smaller, more efficient alternative to bulky vacuum tubes, able to amplify electrical signals and act as a switch in electronic circuits. All three scientists received the Nobel Prize in Physics in 1956, securing Brattain's place in scientific history.
Over his career, Brattain won several awards besides the Nobel Prize, including the Stuart Ballantine Medal in 1952, the John Scott Award in 1954, and the Richtmyer Memorial Lecture Award in 1956. His work was further honored when he was inducted into the National Inventors Hall of Fame in 1974. These accolades acknowledged not only his work on the transistor but also his wider contributions to semiconductor physics and surface phenomena.
In his personal life, Brattain married twice, first to Keren Gilmore Brattain and then to Emma Jane Miller. He kept ties to both his birthplace and adopted homeland, though his career was mostly spent in American research institutions. He spent his final years in Seattle, where he passed away in 1987, leaving behind a legacy that transformed modern technology and electronic communication.
Before Fame
Born to American parents in Xiamen, China, Brattain moved to the United States during his youth. He finished high school at Queen Anne High School and later Tonasket High School. His early studies took him to a few colleges, starting at Whitman College and then transferring to the University of Oregon. The early 20th century was a time of fast progress in physics, especially in understanding atomic structure and quantum mechanics, which gave young scientists chances to make big discoveries.
Brattain did his graduate work at the University of Minnesota and was a leader in solid-state physics research in the 1920s and 1930s. This field was just starting as scientists learned about the electrical properties of crystals and semiconductors, setting up the theory needed for electronics. His doctoral research gave him the experimental skills and theoretical knowledge he needed when he joined Bell Telephone Laboratories, where the telecommunications industry's need for better amplifiers would fuel his key work.
