In honor of Women’s History Month, the Zonta Club of Royal Gorge hosted an author’s luncheon Saturday featuring Jill Tietjen, co-author of “Her Story: A Timeline of the Women Who Changed America.”

Tietjen highlighted women, several of whom are from Colorado, who represent five significant leadership principles: vision, ethics and values, community, stewardship and passion.

The President and CEO of Technically Speaking, Inc., Tietjen is an author, national speaker and an electrical engineer. She is one of the top historians in the country on scientific and technical women. She nominates women of achievement for professional and national awards. Tietjen has been inducted into the Colorado Women’s Hall of Fame.

“Her Story” features more than 850 women in U.S. history from 1587 to 2011.

“These are women most of us haven’t heard of, haven’t learned about in school, haven’t learned their stories,” Tietjen said. “It is my personal mission to tell their stories.”
