Glenn Wenzel was born in the small town of Menasha, Wisconsin. He attended Northwestern College in Watertown, Wisconsin, graduating with a Bachelor of Liberal Arts degree. Following college, he attended Wisconsin Lutheran Seminary in Mequon, Wisconsin graduating with a Master of Divinity degree. He served for 40 years as a Lutheran pastor retiring in 2018.He always had a love of history and became involved in Riverside local history during his years in that city. He shares that love of local history with his wife, Nancy, who was a curator at the Mission Inn Museum and a history interpreter with the Riverside County Parks District. His first climb up Mount Rubidoux was in the spring of 1886 when he accompanied one of his daughter's field trip up the mountain. That sparked an interest in the mountain and its history. A few years later he was asked (by his wife) to give a lecture on Frank Miller and Mount Rubidoux and the Easter service for the docent program at the Mission Inn Museum. In 2010, with the research that he accumulated, he published his first book, Anecdotes on Mount Rubidoux and Frank A. Miller, Her Promoter. Added research and additional collected photographs and other ephemera have resulted in the publication of this his second book, They Climbed the Mountain.Glenn serves on the boards of the Riverside Historical Society, the Friends of Mount Rubidoux and the Riverside County Heritage Association. He was very involved with the Totally Mount Rubidoux Committee who in 2013 raised the funds to purchase at auction the peak of Mount Rubidoux with the cross. In addition to the two books, he has authored over a dozen articles on local Riverside history in local historical journals, four of which are accounts about Mount Rubidoux.
