Carl Victor Page (Larry Page's father, 1938-1996)

Carl is mentioned in The Google Story Chapter 2 "When Larry Met Sergey".

He divorced from Larry's mother Gloria in 1980 or 1981, "when he [Page] was eight years old" according to The Google Story. He then moved on to Joyce Wildenthal, another MSU professor. Larry had a good relation with both Gloria and Joyce:

Larry came to feel that he was showered with love and wisdom from two mothers: his real mom, and Joyce Wildenthal, a Michigan State professor who had a long-term relationship with his dad.

His obituary on the website of the Michigan State University, where he taught most of his life: www.cse.msu.edu/Alumni_Friends/Alumni/PageMemorial.php:

Page served as CSE’s [MSU Department of Computer Science and Engineering] first graduate director and had a critical role in promoting the department’s research mission. In 1967, when he joined MSU, the computer science program consisted of only undergraduate courses. Just three years later, the department offered eighteen graduate courses in computer science.
