Let's make this birthday one to remember.

75 years old (Born on June 14, 1949)

Happy birthday, Harry Turtledove! Your novels have boldly imagined worlds we never knew could be. Whether it's aliens interrupting our little Earth wars or alternate timelines that make readers question history textbooks forever—you've truly proven nothing spices up history quite like a hefty dose of "what if?"

From the gripping Southern Victory series to Worldwar's alien-invasion spectacle, your thought experiments not only entertain but linger long after we've finished reading—and occasionally prompt mild confusion in classrooms around the globe. Here's hoping this year's timeline is everything you ever wanted (without unexpected time-travel hiccups). Happy birthday—we salute your creativity and timeless imagination!
