Who is Nellie Bly (Elizabeth Cochran)? Did she ever win the Pulitzer Prize? If so when?

I’m doing more hw for journalism! I have a huge project on Nellie Bly and the first thing my tutor told me to do was find what she won the Pulitzer prize for and when, and then print that article that won the Pulitzer prize….but everywhere I look, I can’t find anything that says she won the prize. Did she? If so when? And for what article? Any links would be helpful. Thanks in advance.

A little bio of her is included below. She was a noted investigative reporter. But she has not won a Pulitzer Prize. Her most noted work was “Ten Days in a Mad House”.
