# Janis Driver Treworgy

Janis Driver Treworgy (February 6, 1954 – April 7, 2015) was an American academic and sedimentary geologist.

## Early life and education

Treworgy was born on February 6, 1954, in Santa Monica, California. She received her Bachelor of Science from Principia College in 1975. She went to the University of Illinois and received her Masters in 1983 and her PhD in 1985.

## Career

Treworgy was a Paleozoic stratigrapher and sedimentary geologist for 25 years. She made significant contributions towards the creation of a highly detailed network of structural cross sections of the Paleozoic succession in the Illinois Basin.
Treworgy cofounded the Countryside School of Champaign, a K-8 independent school, where she served as the first president of the board from 1992-1995, and a board member until 1999. She also functioned as the Head of School before an official position was created, in addition to filling other roles at the school.
Treworgy was involved with the National Association of Geoscience Teachers (NAGT) since the mid-1990s. She developed the Illinois state curriculum materials for NAGT, later being involved with the organization at a national level and serving as the Central Section secretary/treasurer, 1st vice president, 2nd vice president, and president; and as president helped NAGT transition the Journal of Geoscience Education to an online publication, begin publication of In the Trenches, and establish Geo2YC.
In 2000, Treworgy became a teacher at Principia College. Around that time a mammoth tooth was accidentally unearthed on campus by workman and she led a team to excavate the full mammoth skeleton found in the area, which was a significant find in the central United States. She also led trips for students to study classic geological features around the United States. Treworgy was the chair of the Department of Geology at Principia College and a member of the Illinois State Geological Survey (ISGS). Her research primarily focused on the Illinois Basin particularly the stratigraphy, depositional environments, and tectonic history.

## Personal life

Treworgy was married to Colin Treworgy for forty years and they had two children. They lived in Grafton, Illinois.
She died on April 7, 2015.
