Item Oral history interview with Barbara H. Hornbach(Charles Babbage Institute, 2015-12-10) Hornbach, Barbara H.Barbara Hornbach attended Vassar College where she worked with pioneering computer scientist Winifred Asprey and led the local student chapter of the Association for Computing Machinery. After her graduation in 1969, she began a career in software development and management with Bell Laboratories in Naperville, Illinois. The interview describes her technical work at Bell (on 4ESS and 5ESS) as well as participation in affirmative action committees and workshops within Bell. During 1980-84, Hornbach chaired a standardization sub-committee within CCITT dealing with human-machine interface standards for telephone switching systems.

Sloan Foundation award B2014-07 “Tripling Women’s Participation in Computing (1965-1985).”Item Oral history interview with Joyce Malleck(Charles Babbage Institute, 2008-08-01) Malleck, JoyceJoyce Malleck graduated from Mundelein College with a major in math and a minor in physics, and then received a master’s degree in math from the University of Wisconsin–Madison. She accepted a job at Western Electric and went to work at the Bell Labs facility in Naperville, Illinois. She did programming courses at the corporate training center in Princeton NJ, learning COBOL, assembler, PL/1, and a proprietary Bell database management language. (She later did a MBA at the University of Chicago, completed in 1980.) An early assignment was programming to direct an automatic wiring machine for the ESS manufacturing. She was promoted to department chief, initially maintaining a data center’s operating system then doing software and database development for the customer side of ESS. In the 1970s she started a software quality department, which involved greater attention to written formal specifications, code reviews, and structured developmental processes — software engineering. Leaving Bell in 1989, she worked for Motorola for ten years as a product manager and consultant to industry. She compares Bell’s and Motorola’s treatment of and attitudes to women, relating insightful personal anecdotes. This material is based on work funded by the Alfred P. Sloan Foundation award B2014-07 “Tripling Women’s Participation in Computing (1965-1985).”Item Oral history interview with Karen Coates(Charles Babbage Institute, 2015-12-14) Coates, KarenKaren Coates grew up in rural northwest Washington state, then graduated from Mills College (Oakland CA) with a degree in mathematics. She describes lessons learned in running FORTRAN programs at nearby Cal State Hayward, a summer internship at IBM, and then work with UC Berkeley’s Laura Gould that led to computer-science teaching at Mills and at Stanford University. Continuing her computer science education at Northwestern University, she met many Bell Labs women working there on master’s degrees and applied herself for a job at Bell Labs. She began work at Bell Labs Naperville in 1974 as a Member of Technical Staff assigned to 4ESS then moved to the Computation Center and worked on the Bell Laboratories Network, an early packet-switched network. She describes working at Bell’s Murray Hill (NJ) facility with Bjarne Stroustrop, during the time he developed “C with Classes” which evolved into C++. Returning to Naperville/Indian Hills, she took up managerial positions in the networking project and then in switching-system applied research. She relates her experiences with the 1970s women’s movement and the supportive network of women colleagues. She left Bells Labs in 1985 and moved to California, where she worked for a subsidiary of TRW on military intelligence systems; a communications company called Octel; a startup venture; and a health-care enterprise celled Omnicell. She describes subtle transformations in gender discrimination in the 1980s and in Silicon Valley. This material is based on work funded by the Alfred P. Sloan Foundation award B2014-07 “Tripling Women’s Participation in Computing (1965-1985).”
