The Armchair Team

Our team members here at The Armchair Historian

David Mainayar

Market Lead, Editor

My name is David Mainayar, and I’ve been fascinated by history since I was a kid. The first era that captured my imagination was the Middle Ages, but, through the combination of voracious reading, documentary-watching, podcast-listening, as well as frequent trips to Europe, that spark has since matured into a flame, leading me to learn about a range of historical topics with a fiery sense of curiosity.

I began working with The Armchair Historian channel in March of 2018 after becoming a longtime fan. My duties have ranged from research and script-writing to marketing and social media outreach. I am currently an intended Business Administration major at the University of California, Berkeley and enrolled in two history courses, one covering Middle Eastern history and the other encompassing the history of Italy from the Renaissance onward.

Griffin Johnsen

Founder, Producer

My name is Griffin Johnsen, also known as "The Armchair Historian." I have felt passionate about history ever since I can remember, being greatly influenced by my grandfather Norman, who served in the 52nd Air Defense Artillery Regiment as a Master Sergeant during the Second World War. Together, we watched countless documentaries and talked about his experiences in the war. After he passed away in 2008, I kept him close to heart and continued studying. Eventually, I decided to start my Youtube Channel in June of 2016 when I was seventeen years old. I called it "The Armchair Historian."

Despite the channel name, however, there is more to the channel than just me. On the team, we have an artist as well as multiple researchers and script-writers all working diligently to produce well-made and informative history videos.

Gert Bos


My name is Gert Bos and I am an illustrator of profession. A long time ago I started making comic strips as a hobby and after a while I could sell it. Then I also started drawing illustrations and cartoons and over the years I have improved my skills in different drawing styles and working with different tools.

I met Griffin Johnsen online at a place where illustrators and clients can find each other for new jobs. We immediately found a good form of cooperation and since January of this year I have been involved in the graphic work of all videos of the Armchair Historian. I have a lot of fun making suitable illustrations, but I also like this job because of the information I get about the different history topics. Because I used to have difficulty concentrating at school during classes, I can now catch up on my knowledge :)
