Let's make this birthday one to remember.

84 years old (Born on February 06, 1941)

Happy Birthday, Spencer Silver! Your brilliant invention of a reusable adhesive has truly stuck around—literally. Thanks to you and Arthur Fry, forgetful people everywhere have found salvation in the humble Post-It Note. Who knew that something designed not to stick too strongly would become one of life's strongest essentials?

Your groundbreaking work earned 3M's highest honors—and rightly so! You've proven that sometimes the best ideas come from experiments gone slightly awry. Here's hoping your birthday is filled with joy, laughter, and plenty of colorful reminders (on Post-Its!) about how much you're appreciated for making our lives easier every day.
