Nellie Bly died of pneumonia at St. Mark's Hospital in New York City at the age of 57. This date marks the end of the life of a groundbreaking journalist who paved the way for future generations of female reporters and investigative journalists.

Nellie Bly married millionaire manufacturer Robert Seaman. Bly was 31 and Seaman was 73 when they married. This marked a temporary shift in her career, as she stepped back from journalism to focus on her marriage and, later, her husband's business.

Nellie Bly completed her record-breaking trip around the world, arriving back in New York City just over 72 days after her departure. This feat solidified her fame and placed her in the history books as a pioneering journalist and adventurer.

Nellie Bly embarked on her journey around the world from New York City at 9:40 a.m. aboard the Augusta Victoria. This voyage was an attempt to beat the fictional record set in Jules Verne's 'Around the World in Eighty Days' and was a major publicity stunt for the New York World newspaper, marking a significant event in the history of journalism.

Elizabeth Jane Cochran, later known as Nellie Bly, was born in Cochran's Mills, Pennsylvania. This date marks the beginning of the life of a pioneering journalist and investigative reporter who would later become famous for her undercover work and her record-breaking trip around the world.
