Albert Einstein
Albert Einstein was a certified genius, and his contributions to science are immeasurable. However, he was also a deadbeat dad. It’s disappointing to hear that he forced his wife to give up their first child and then refused to acknowledge his other kids. I get that he was busy thinking about E=mc² and all that.
But come on, man; your kids need love too. And don’t even get me started on his involvement in the Manhattan Project. It’s like being the star quarterback of your high school football team and then denouncing the game after you graduate. Even the most brilliant minds have their blind spots.
