Biography

David was born in the 1950's to Tom Grawrock and Cyphert in Tennessee. His father being the the US Navy, they moved often. David spent 6 wonderful weeks in Tennessee, has very found memories, and hasn't been back since. A succession of transfers and cruises had David living in Massachusetts, Rhode Island, Long Island, Florida, San Diego, Guam, China Lake, and then Poway. He graduated High School from Poway High.

He married his high school sweetheart, Parker in the Church of Jesus Christ of Latter Day Saints, Los Angeles Temple in the 1970's.

David was a member of The Church of Jesus Christ of Latter-day Saints.

Moving around chasing jobs the family lived in San Diego, Poway, Pocatello, San Jose, West Valley City, South Jordan, Londonderry, and Aloha. His career in high tech took him to some industry leaders including Lotus Development, Central Point/Symantec, and finally Intel, from which he retired in the 2010's.

David was intimately involved with the Trusted Computing technologies[1] which started development in the early 2000's. He was the workgroup chair and editor of the Trusted Platform Module (TPM) specification. Which is standardized by International Standards Organization (ISO) as ISO/IEC 11889-1 [2]

After retirement, they moved to Southern Utah where David is working on his passions of hiking, photography, and, oh yes, genealogy.

Famous Relatives

Currently, unless one goes way back, there are not really any famous relatives. They are a mixed group, but just ordinary people who've lived life.

Patents

On a personal note, John Grawrock was an inventor. But also a gambler and supposedly lost his company to those who he owed gambling debts.[3] What is interesting is that David is also an inventor. His list of patents is at the US patent office.[4]

His goal is to have more patents than John. Currently, as of 27 Dec 2019, David is at 79 and John at 3. The issue is that it's very difficult to directly search for patents prior to 1972. The 3 currently located ones were all filed and issued on the same days. See John Grawrock for the list.

Hi David,

Thanks for taking the Pre-1700 Quiz!
