The March session of Wartburg College’s Keep on Learning series will explore inventions pivotal to the modern world.

Michael L. Sherer, editor emeritus of the Metro Lutheran and a 1963 Wartburg alumnus, will present “Grand and Glorious Game-changers” on Thursday mornings — March 7, 14, 21, 28.

Inspired by “The Discoverers,” a book by Harvard historian Daniel J. Boorstin, the course will consider the impact of time-measuring devices, magnifying lenses, the compass and the printing press.

Keep on Learning sessions meet in the Heritage Room of Saemann Student Center, beginning with coffee at 9 a.m., followed by the presentation from 9:30 to 11:30 a.m. Parking is available near Saemann Student Center for those entering campus on Wartburg Boulevard.

Pre-registration is not required, and a $30 fee is payable at the second class.

The Wartburg Alumni and Parent Relations Office coordinates Keep on Learning with the assistance of a volunteer committee. For more information call 319-352-8491 or e-mail alumni@wartburg.edu.
