Early Life and Education

William Henry Green II was born on May 5, 1980, in Birmingham, Alabama, and moved to Orlando, Florida.

His father, Mike Green, and mother, Sydney Green, raised him alongside his older brother John Green, a future bestselling author.

Hank attended Winter Park High School, graduating in 1998, where he explored science fairs and early video projects.

He pursued a Bachelor of Science in biochemistry at Eckerd College, earning his degree in 2002, before completing a Master of Science in environmental studies at the University of Montana in 2006, experiences that ignited his passion for blending education with digital storytelling.

He is of white ethnicity, and keeps his religion private.

Career

Hank Green began his professional journey in the mid-2000s as a web developer, creating sites for educational institutions and environmental nonprofits while studying in Montana, but his creative pivot came in 2007 when he and brother John launched Vlogbrothers—a year-long “no-text” video challenge that exploded into a weekly series exploring science, culture, and absurdity, amassing over 2,300 videos by early 2025.

This foundation birthed the Nerdfighteria community, leading to the annual Project for Awesome, which has raised millions for charities, and his first music album, So Jokes (2008), infused with community-themed tracks.

Green’s early engineering gigs, including work on MRI machines and exploration vehicles, informed his content’s authenticity, setting the stage for his shift to full-time creation.

Green’s influence surged in the 2010s with the launch of Crash Course in 2012, co-produced with John to cover high school curricula from biology to literature, reaching 14.6 million subscribers, and SciShow in 2012, a quirky science explainer that hit 7.44 million subscribers by explaining everything from quantum physics to everyday myths.

He co-founded VidCon in 2010, growing it into the premier online video event, and DFTBA Records to support indie artists, while authoring young adult novels like An Absolutely Remarkable Thing (2018) and its sequel A Beautifully Foolish Thing (2019), which topped bestseller lists and explored AI and fame.

Collaborations with creators like Simone Giertz and Mark Rober amplified his reach, alongside stand-up specials and podcasting on Hello Internet with John.

Hank Green sustains his momentum through resilient ventures, including the 2023 launch of Open Sauce, a maker convention uniting STEM influencers, and the 2024 comedy special Pissing Out Cancer on Dropout, rawly chronicling his Hodgkin lymphoma diagnosis and recovery that forced a CEO step-back from Complexly.

By 2025, he debuted the productivity app Focus Friend with Honey B Games and revived Ask Hank Anything on Complexly’s YouTube, interviewing figures like Michelle Khare, while Good Store—umbrella for Awesome Socks Club and Awesome Coffee Club—surpassed $10 million in donations.

His work continues to educate and entertain, championing science literacy amid global challenges.
