William O. Baker (1915-2005) was a prominent research chemist, head of Bell Laboratories, and a frequent advisor to the government on scientific affairs and technology. His government service spanned from the Truman administration through the Bush administration and focused on intelligence gathering and national security issues.

The Writings series contains copies of Baker's speeches and articles, typically either offprints or photocopies of publications, with the majority written after his retirement from Bell Labs in 1980. Earlier writings, before 1955, were predominantly technical science papers related to his own chemistry research at Bell Labs. Beginning in 1955, his writings were concerned with the overall focus of Bell Lab's research, communications science and technology, the impact of science on business and government, government support for research, and general analyses on conducting scientific research. Beginning in the 1970s, he also frequently wrote about encouraging innovation in research, the role of science and technology in government and society, and the education system, especially in the sciences. After his retirement in 1980, in addition to continuing to write about these subjects, he also wrote about the future of technology and information systems. Baker also wrote about national materials policy periodically throughout his career.

The Correspondence series spans Baker's entire career at Bell Labs, as well as his advisory work and his retirement. The majority of the correspondence is between Baker and other scientists and scholars discussing recent papers and issues in their fields, as well as invitations to Baker for events and speaking engagements and congratulations to Baker for his various promotions, appointments, and awards. The series also contains correspondence related to his membership and leadership in professional organizations, the management of Bell Labs, correspondence with government officials related to his service on committees and as an advisor, and phone messages taken for Baker.
