Let's make this birthday one to remember.

84 years old (Born on April 28, 1941)

Happy Birthday, Dr. Karl Barry Sharpless! You're truly the master of molecular matchmaking—uniting atoms in elegant, stereoselective relationships. Thanks for teaching us that chemistry isn't just about bonds and reactions; it's about making sure molecules find their perfect partners (preferably without drama!).

Your groundbreaking clicks and twists deserve plenty of celebration—and perhaps a Nobel Prize or two? Oh wait—you already have those! Your remarkable double-Nobel success has set quite an exclusive chemistry club. May your birthday be filled with as much joy and laughter as you've brought to chemists everywhere through your ingenious reactions and boundless curiosity!
