Summary

This oral history interview, conducted by Tom Gardner for the Computer History Museum, captures Don Mattson’s career in technology manufacturing, spanning over 50 years. Mattson begins with his family background and education at Berkeley, including an MBA, followed by an Army stint in Italy. He then worked at Eitel-McCullough, a vacuum tube manufacturer, where he developed early clean-room techniques for ceramic-to-metal sealing. In 1969 he moved to Memorex, initially in disk pack production and then as production manager of the tape plant, where he details the 1961-vintage tape manufacturing process: vibratory ball mills for dispersing iron oxide, reverse-roll coating, drying, calendaring, and slitting, along with environmental and safety challenges. He later led the disk pack division through the transition to Winchester data modules, then ran manufacturing at Verbatim, founded a thin-film disk company, consulted via PRTM, and served as COO of InVision Technologies, scaling up CT explosive-detection scanners after 9/11. The interview concludes with the sale of InVision to General Electric. Throughout, Mattson provides a rare manufacturing perspective on Silicon Valley’s hardware evolution, emphasizing clean room practices, process control, and organizational leadership.

Critical Evaluation

Value of the Information & Strength of the Argument

The value of this interview lies in its rare focus on the manufacturing side of computer storage, an area often overshadowed by design and engineering. Mattson offers concrete technical details—such as the use of vibratory mills with cylindrical alumina media, the challenges of dispersing iron particles, and the subtleties of clean room contamination—that enrich our understanding of early production processes. His argumentation is grounded in personal experience, avoiding speculation and providing specific anecdotes (e.g., the first tape line startup misfeed). The narrative is coherent and persuasive, demonstrating how manufacturing constraints shaped the success of companies like Memorex and InVision.

Scientific Rigor, Source Quality, Title Accuracy

The content is drawn directly from Mattson’s recollections, with no external sources cited within the video itself. The description provides a link to the Computer History Museum’s catalog entry for the interview, which includes a transcript and context. As an oral history, the rigour is inherent to the genre: while primary and deeply informed, it is subject to memory lapses and retrospective bias. The title ‘Oral History of Don Mattson’ is perfectly aligned with the content, as the video is a straightforward interview rather than a scripted documentary. The interviewer’s questions are neutral and encouraging, allowing Mattson to elaborate freely, which supports authenticity.
