Who created Gettysburg by the Numbers (GBTN)?

GBTN is a project from TeachersFirst, a free, ad-free teacher resource web site that has been a free service of the non-profit The Source for Learning since 1998. Learn more about TeachersFirst here.

GBTN was researched and written in a collaborative effort by members of the TeachersFirst team, including Candace Hackett Shively, M.A., Peggy Jennings, Ed.D., and our extensive team of teacher-reviewers. Gettysburg by the Numbers, like all of TeachersFirst, was written by experienced teacher-leaders who know the realities of the classroom and model best practices in creation and use of digital media for learning.

The visual design, infographics, and illustrations in Gettysburg by the Numbers were created by the team of Rita Lee (designer) and Rick Henkel (illustrator) in collaboration with the TeachersFirst team.

Selected Gettysburg photographs and historic consultation were provided by David W. Shively.

The technical work to make Gettysburg by the Numbers come to life as a web site was done by Jay Volk.
