The innocent-looking book in this photograph grew up to be one of the most evil men in the world.
On a spring day in May 1960, a baby boy was born in Milwaukee, Wisconsin.

His parents, a chemistry student and a teletype machine instructor, welcomed their firstborn son with hope and dreams for his future.
By all accounts, he was an ‘energetic and happy child’ in his earliest years, per A&E, full of life and promise.
But something changed.

Shortly before his fourth birthday, the little boy underwent double hernia surgery. His family noticed an immediate shift in his personality.

The energetic, bubbly child became notably subdued and withdrawn. At elementary school, teachers described him as quiet and timid, often detecting signs of abandonment as his father’s studies kept him away from home and his mother suffered from depression and hypochondria.
