At Noah's, she wrote a regular women's column, focusing on such traditional subjects as fashion, cooking and the arts.

There was great resistance from male editors about hiring a woman to cover news or do serious reporting outside of what was considered women's sphere.

[4] As a result of her journalism career, she met her husband, fellow journalist and editor for the New York Herald, David G. Croly.

[5] While most women were expected to abandon their career after marrying, Jennie June continued to work, and did so after having children.

This magazine was devoted to women's fashions, and Jennie became known as an expert in the subject, widely quoted in other publications.

Schlesinger argues that "Croly's lasting contribution to the progress of American women was her insistence that sex be submerged in competent performance".

She told American women that financial independence and economic equality was as or more important than the right to vote.

[10] In her later years, Jennie June Croly was often referred to in the press as the "Mother of Women's Clubs", a term that was also mentioned when newspapers reported on how she became ill in the summer of 1898.

[12] She made a trip back to England, to see the country of her birth after so many years away and, after returning to New York, she died of heart failure, on December 23, 1901, at the age of 72.
