History isn’t always shaped by grand plans, sometimes it turns on pure chance. A wrong turn, an accidental discovery or a split second decision has changed the world in ways no one could have predicted. Here are six people who altered history by accident. (unsplash)

Christopher Columbus; A wrong route changed the world: In 1492, Christopher Columbus set sail hoping to find a faster route to Asia. Instead, he landed in the Caribbean, unaware he had reached an entirely different part of the world. That mistaken voyage reshaped trade, exploration and global history forever. (wikimedia commons)

Princip seized the unexpected opportunity and assassinated the Archduke, triggering World War I. (wikimedia commons)

Rosalind Franklin, A photo that changed science: Rosalind Franklin was studying coal and molecules when her X-ray diffraction image of DNA, known as Photo 51, captured a crucial detail. That image became key to understanding DNA’s double helix structure, transforming genetics and modern medicine in ways few could have imagined. (wikimedia commons)

Roy Plunkett, A failed experiment created Teflon: Chemist Roy Plunkett was trying to develop a new refrigerant in 1938 when a gas canister mysteriously stopped releasing. Inside, he found a slippery white substance: polytetrafluoroethylene, later known as Teflon. (science history institute)
