Larry Pages's older brother.
It is hard to find information on this little bugger! Not a single photo online!
As suggested by the "Jr.", he is named after Larry's father, Carl Victor Page.
Carl Jr. is mentioned in a few places in the book The Google Story. The full name "Carl Victor Page Jr." is never given in that source, only "Carl Page Jr." is used. These crazy Anglo-Saxons and their semi-optional middle names!
The Google Story does not cite its sources, but it likely got much of its insider information through interviews, e.g. Chapter 2. "When Larry Met Sergey":
Carl Jr. recalls Larry as an inquisitive younger brother with wide-ranging interestswhich suggests the authors actually interviewed Carl Jr., since interviews with Carl Jr. cannot be found anywhere else on the Internet. It would be interesting to know more how they got that level of access.
Chapter 2 mentions that Carl Jr. is nine years older than Larry. Therefore, he must have been born in 1963 or 1964. It also states that Carl studied at the University of Michigan, like his father and like Larry would also do later on:
He also enjoyed helping Carl Jr. - who was nine years older - with his college computer homework when Carl came home from the University of Michigan during breaks.Their father was a professor at the Michigan State University, which is a different university from the University of Michigan, and not in the same city, so by breaks they mean term breaks.
Chapter 2 also mentions that he was working in Silicon Valley by the time their father died in 1996:
Despite his grief [for the death of their father at the early age of 58], Larry remained enrolled at Stanford. It helped that his older brother, Carl Jr., lived and worked in Silicon Valley. They had each other, so Larry wasn't left to bear the loss alone, and the two spent time together, fondly recalling their dad and reflecting on their childhood memories.
In 1997, Carl co-founded the mailing list management website eGroups together with Scott Hassan, programmer of an early version of Google when he was a research assistant at Stanford University. Carl and Scott presumably met through Larry, but we don't have a source. The company was sold to Yahoo! in 2000. The Google Story Chapter 8. "A Trickle" mentions:
Google's deal with Yahoo!] had special significance for Larry Page, since his brother, Carl Jr., also was in serious negotiations with Yahoo! over a major business transaction. The following day, June 27, Yahoo announced plans to buy eGroups, a technology firm that Carl Page had co-founded, for $413 million.Carl is listed as a co-founder in the SEC filing: www.sec.gov/Archives/edgar/data/1105102/0000950149-00-000584.txt as "Carl Page". He does not appear on the 5% stockholders however, poor Carl.
In 2006, he brought a company he founded called "Handheld Entertainment" public through a reverse merger with a shell company: archive.nytimes.com/dealbook.nytimes.com/2006/03/21/brother-of-google-co-founder-uses-shell-company-for-handheld-start-up/. "Handheld Entertainment" made an iPod competitor apparently. SEC filing: www.sec.gov/Archives/edgar/data/1309710/000095013606009480/file1.htm.
September 27, 2023 marked Google's 25 th aniversary and the page cirosantilli.com/carl-victor-page-jr had a small surge of views according to Google Analytics. On that day, this page was one of the top Google search results for "Carl Victor Page, Jr."[ref]. Wikipedia also had a large bump in searches for "Larry Page" on the same day: pageviews.wmcloud.org/?project=en.wikipedia.org&platform=all-access&agent=user&redirects=0&start=2023-09-11&end=2023-10-01&pages=Cat|Dog|Larry_Page which must be the root cause, Larry actually managed to beat "Cat" and "Dog" on that day.
