This is How Smiles in Yearbook Photos Have Changed Over the Past 100+ Years

Smiling is a relatively recent phenomenon in the history of photography. If you take a look at photos from many decades ago, people commonly wore stoic expressions on their faces and portraits were a much more serious affair.

Researchers at UC Berkeley recently crunched through an enormous trove of high school yearbook photos to show how smiling and portraits have evolved over the past 100+ years.

Retired PE Teacher Wore the Same Outfit for 40 Years’ Worth of Yearbook Photos

It started out as a mistake. Back in 1973, PE teacher Dale Irby wore an era-appropriate polyester shirt and brown sweater-vest to picture day. The next year, entirely by accident, he wore the exact same thing. At first he was horrified, but the next year, his wife Cathy dared him to do it again.

What started as a mistake, turned into a dare, and then ultimately into a 40-year tradition that ended this year when Irby chose to retire.
