About Zach Weinersmith
Born 1982. Zach Weinersmith is an American writer, draftsperson, illustrator and webcomic, known for Saturday Morning Breakfast Cereal.
Zachary Alexander Weinersmith (né Weiner; born March 5, 1982) is an American cartoonist and writer, best known for his webcomic Saturday Morning Breakfast Cereal (SMBC). Outside of SMBC, he has worked on a sketch comedy series, a podcast, and multiple other webcomics. With his wife Kelly Weinersmith, he has co-authored the 2017 book Soonish and the 2023 book A City on Mars. He illustrated the 2019 book Open Borders by economist Bryan Caplan, and wrote the 2023 children's book Bea Wolf, a loose adaptation of Beowulf.
Background and personal life According to Weinersmith, his great-grandfather immigrated to the United States in 1925, and he has no family in Europe as they were killed in the Holocaust. Weinersmith describes being "raised Jewish, in an only casually religious environment".
Weinersmith has been writing and drawing comics since high school, often using the name "Saturday Morning Breakfast Cereal" for these comics. His early webcomics usually had three or more panels, but in 2002 he switched to a single-panel format.
Weinersmith graduated from Pitzer College in California with an English degree in 2003. He then worked in the film industry for around two years, including at The Asylum, and later a talent agency.
While in California he met Kelly Smith, then a graduate student at U.C. Davis, later an adjunct professor at Rice University. They married, and both took the combined surname Weinersmith. They have two children, Ada and Ben. The Weinersmiths reside in Charlottesville, Virginia.
In an interview in 2009, Weinersmith described his personal philosophy as "pragmatic" and said he is "probably" agnostic, saying "though I’m probably not willing to call myself an atheist per se, I almost certainly behave like an atheist, when it comes to specific activities related to spirituality."
Weinersmith's first version of SMBC was a character-based three-panel strip done while he was in college. 27 Nerd Disses: A Significant Quantity of Disrespect (2013) is an e-book of nerdy insults co-written by Weinersmith and Phil Plait and illustrated by Jess Fink. Augie and the Green Knight (2015) is a children's book written by Weinersmith and illustrated by Gilles Roussel (known as Boulet). The book features an adventurous and scientifically minded female protagonist in a retelling of the medieval romance Sir Gawain and the Green Knight. Weinersmith said it was an attempt to give his daughter a book "about little girls who are smart, and scientific, and (here's the crucial thing) risk-taking." The book was financed through the crowdfunding website Kickstarter, receiving $US384,410. Soonish (2017) is a collaboration between Weinersmith and his wife Kelly Weinersmith looking at upcoming technologies that could change the future. The book reached multiple New York Times Bestseller lists. Open Borders: The Science and Ethics of Immigration (2019) is an illustrated book about the history and potential benefits of open border policies, co-written with Bryan Caplan. Bea Wolf (2023) is a children's book written by Weinersmith and illustrated by Gilles Roussel (known as Boulet). The book is a retelling of the Beowulf tale. A City on Mars: Can we settle space, should we settle space, and have we really thought this through? (2023) is a popular science book on space settlement and challenges facing a potential colonization of Mars, colonization of the Moon, and related activities. Sawyer Lee and the Quest to Just Stay Home (2026) is a children's book about a child's attempts to avoid going on an adventure. Collections of SMBC comics have also been published in physical books.
