Alan Cohen, who died on May 7, 2019 was a retired psychologist who lived in Berkeley.  He wrote a  book, A History of Berkeley From the Ground Up, and published it online.  (Parts are at the old URL, http://www.historyofberkeley.org/, which has been appropriated by a non-English speaker, but the entire manuscript is archived at https://web.archive.org/web/20171014035224/http:/historyofberkeley.org/index.html.) ~~annh 7/7/19

Previously entered in this wiki:

His book on Horace Carpentier remains unfinished although it is hoped that his partner in this endeavor may be able to finish it.

He authored the book A History of Berkeley - From The Ground Up. In his book which he has posted in its entirety online, he notes that the early history of Berkeley, is in fact the early History of Oakland, as Berkeley was part of the original Oakland Township before splitting off on its own.

He met me, HiMY SYeD, in the Oakland History Room during our Big History Editathon, and I showed him OaklandWiki. He showed me his book's website. He's allowed any of the photographs in his book's photo gallery, to be re-posted here on any OaklandWiki pages. ( Yay! )

His next book will be about Horace Carpentier, who once owned more land than anyone else in Alameda County.

Dr. Cohen has also offered to be a resource for any OaklandWiki people on anything Oakland History related.
