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.
