Oskar Schindler was an unexpected hero. He drank heavily, and some even said he was a womanizer who flaunted his affairs. Yet, in one of history’s darkest hours, he demonstrated an extraordinary capacity for courage and humanity.

Margaret Thatcher, famously known as the “Iron Lady” due to her tough-as-nails personality, was not only Britain’s first female prime minister, but one of the most influential political leaders of the 20th century. She commanded the spotlight at a crucial moment in both British and world history. Although she had her problems along the way—dealing with the Cold War, incursions at the Falkland Islands, and attacks by the IRA, at one point almost losing her life in the process—she rose to the occasion.

London was a tinderbox waiting to ignite. An unusually hot and dry summer had drained the city’s water supplies, and without an organized firefighting force, its citizens were left to fend for themselves. The stage was set for catastrophe, and in the early hours of Sunday, September 2, 1666, the spark was struck. A seemingly inconsequential fire ignited in a baker’s shop on Pudding Lane. Unchecked and underestimated, it would grow to become one of the most devastating disasters London had ever faced.

Rosalind Franklin was what can only be called an overlooked genius. Although she was not fully credited for the feat at the time, her work led to major breakthroughs in our understanding of DNA. In fact, she took the first X-ray photo of DNA in all of its double helix glory. By the time her former colleagues were being showered with accolades for results they made at least partially based on her findings, Franklin would not be around to see it. Sadly, it’s believed that her use of X-ray equipment gave her terminal cancer, cutting her life short at age 37.

One of Hitler’s most notorious henchmen, Hermann Göring was the bulldog who obediently followed orders while destroying countless lives. In his early career as the leader of the SA, also known as the Brownshirts or Stormtroopers, Göring played a pivotal role in suppressing any and all opposition to the Nazi Party. He was also implicated in the Reichstag Fire of 1933, an event that resulted in the suspension of civil liberties in Germany and greatly aided in the consolidation of Nazi control.
