Hannah Kalvin, our Marcy Gross intern, Spring 2016

Hannah became a Marcy Gross intern during the second semester of her internship at NCHR during her senior year.  “After proving herself such a valuable asset to our Center, we wanted to show our appreciation by giving her an internship named for one of our most important supporters,” explains NCHR president Diana Zuckerman.  Marcy Gross was a nationally respected voice on women’s health issues – many of the same issues that Hannah is working on at NCHR.  A major focus is women’s access to medically necessary procedures, collecting data and analyzing health insurance plans as a part of the NCHR Affordable Care Act project.

Hannah will be graduating in May from the George Washington University with a Bachelors of Science in Public Health and a minor in Biological Sciences. Hannah developed a passion for public health after learning about different health disparities in her first public health course in college.

In Memoriam

Gwendolyn Lewis, a former sociology professor with important positions in the National Research Council, National Science Foundation, and U.S. Department of Agriculture, was a professional photographer who volunteered her time as our photographer since our founding in 1999 until she died from cancer in 2012.

As our photographer and friend, Gwen is responsible for the many memorable color photographs of the exceptional women who received our Foremother awards, as well as capturing many other important people and moments through the years.  As an artist, however, she specialized in black-and-white photography, with an emphasis on architectural subjects. Her work was exhibited in more than 100 shows in the Washington area and won many awards.
