In 1876, in the year that Maria Duwa was born, on February 14th, Alexander Graham Bell applied for a patent for the telephone. So did Elisha Gray. A month later, on March 7th, Bell was granted the patent and on the 10th, he made his first successful telephone call - in which he said: "Mr. Watson, come here, I want to see you."

In 1880, she was just 4 years old when on February 4th, five members of one family in Ontario, Canada were killed and their farm was burned by a mob. Called the Black Donnelly Massacre, the Irish family had been feuding with other citizens of the town. No one was ever convicted.

In 1898, in the year of Maria Duwa's passing, magnate and philanthropist John D. Rockefeller's Standard Oil Company controlled 84% of the oil and pipelines in the United States. Rockefeller grew Standard Oil through the merger of several other small oil companies throughout the U.S., creating a monopoly.
