'''David Beauregard Bogy''' (Dave Bogy) is the William S. Floyd, Jr. Distinguished Professor of the Graduate School at the University of California, Berkeley (UCB).<ref name=bio/> He is also the founder and head of the Computer Mechanics Laboratory (CML) at UCB..<ref name=cml>{{Cite web|url=http://cml.berkeley.edu/about_new.html|title=CML – About|website=cml.berkeley.edu}}</ref> He has made particular contributions in air-bearing analysis and design for the sliders that support the read/write heads in hard disk drives (HDD).<ref name=bhushan>[https://books.google.com/books?id=24bMBQAAQBAJ&pg=SA16-PA27 G.

==Background and education== He attended the local school in Wabbaseka until 10th grade when he transferred to Columbia Military Academy, Tennessee joining the ROTC.<ref name=oral>{{Cite web|url=https://www.youtube.com/watch?v=KBbZ-e7yIBw|title=Oral History of David Bogy|date=2 January 2018 |via=www.youtube.com}}</ref><ref>{{Cite web|url=https://www.computerhistory.org/collections/catalog/102738449|title=Bogy, David oral history|date=August 28, 2017|publisher=Computer History Museum|via=Computer History Museum Archive}}</ref>
Bogy attended Rice University from 1954 to 1961. He received dual B.S. degrees in 1959 in mechanical engineering and geology and then went on to receive a M.S. degree in mechanical engineering in 1961. Between 1961 and 1963, he fulfilled an obligation to spend time in the US military and served in the US Corps of Engineers at Fort Leonard Wood.<ref name=oral/> From 1963 to 1966, he attended Brown University where he received a Ph.D. in applied mathematics working on elasticity under Eli Sternberg. From 1966 to 1967, he was a postdoctoral fellow at the California Institute of Technology also studying under Sternberg. It was at this time, that he first gained recognition for his analysis of mechanical stress concentrations at sharp corners.<ref>.[https://asmedigitalcollection.asme.org/appliedmechanics/article-abstract/35/3/460/385497/Edge-Bonded-Dissimilar-Orthogonal-Elastic-Wedges D.

==Career==
In 1967, Bogy interviewed with Paul Naghdi at the University of California, Berkeley and subsequently joined the Department of Mechanical Engineering where he has spent his entire career.<ref name=oral/> He was promoted from assistant professor to associate professor in 1970 and then to full professor in 1975. From 1991 to 1999 he was chair of the Department of Mechanical Engineering. In 1993, he was appointed the William S. Floyd, Jr. Distinguished Professor.<ref name=bio>[http://cml.berkeley.edu/SM_Program.pdf UCB Computer Mechanics Laboratory 31st Annual Sponsors' Meeting, pp. 148–149, Jan. 28th, 2019]</ref>
Around 1972, Bogy took a summer position at IBM Research Almaden where he collaborated with Frank Talke<ref>{{Cite web|url=https://cmrr.ucsd.edu/research/faculty-profiles/talke.html|title=Frank E. Talke|website=cmrr.ucsd.edu}}</ref> and was introduced to magnetic recording as a discipline. By 1984, Bogy was actively working on Hard Disk Drive mechanics contracted out from the newly established Center for Magnetic Recording Research at UC San Diego.<ref>{{Cite web|url=https://cmrr.ucsd.edu/_files/newsletters/old-series/vol1-84.pdf|title=CMRR Report Vol. 1, p. 2, 1984}}</ref> By 1989, Bogy had taken the initiative and established the Computer Mechanics Laboratory (CML)<ref name=cml/> at Berkeley specifically to support the Hard Disk Drive (HDD) industry.<ref name=oral/> It was one of the first research groups to employ laser Doppler vibrometry in HDD measurements.<ref>{{Cite journal|title=Dynamic response of a Winchester-type slider measured by laser Doppler interferometry|first1=D.|last1=Miu|first2=G.|last2=Bouchard|first3=D.|last3=Bogy|first4=F.|last4=Talke|date=September 19, 1984|journal=IEEE Transactions on Magnetics|volume=20|issue=5|pages=927–929|doi=10.1109/TMAG.1984.1063300|bibcode=1984ITM....20..927M }}</ref> The center is now particularly noted for the software tools for the air-bearing design for the sliders that support the read/write heads.<ref name=bhushan/><ref>{{Cite web|url=http://cml.berkeley.edu/index.html#|title=Computer Mechanics Lab.

Bogy has supervised some 66 Ph.D. degree students. About one third of these have gone on to become professors in research universities and most of the remainder work in the computer disk drive industry.<ref name=oral/> Two notable students are George Adams and Richard Benson.<ref>{{Cite web|url=https://chairs.utdallas.edu/profiles/dr-richard-c-benson/|title=Dr. Richard C. Benson – Endowed Chairs and Professorships | The University of Texas at Dallas}}</ref>
Bogy has authored or co-authored over 400 technical papers. The early papers were on mechanical stress and fluid flow (inkjet), but the majority since 1984 have focussed on the mechanics of hard disk drives and on the air-bearing design and dynamics of the slider and its interaction with the disk surface (the ceramic slider carries the read/write heads). Many of the papers are highly cited (h-index = 48).<ref>{{Cite web|url=https://www.researchgate.net/profile/David-Bogy-2|title=Researchgate: profile: David Bogy}}</ref><ref>{{Cite web|url=https://typeset.io/authors/david-b-bogy-40q66bxoi8|title=David B.
