Join us for a special lecture from the Smithsonian’s Making History, Making Change Lecture Series right here in Colorado. The specific speaker, a Smithsonian curator, scientist, educator, historian, or other expert, will be announced soon! The Making History, Making Change Lecture Series is a significant part of the Smithsonian’s national programming in 2026 to commemorate the 250th anniversary of the signing of the Declaration of Independence. The Smithsonian and 25 Affiliates across the country (including History Colorado) will collaborate to celebrate, explore, and commemorate this milestone while illuminating national and regional stories and their contributions to our nation’s history.
This lecture is part of the 2025-2026 Rosenberry Lecture Series. Purchase tickets to multiple lectures in the series here.
About the Making History, Making Change Lecture Series
Each Making History, Making Change Lecture will feature a Smithsonian curator, scientist, educator, historian, or other expert who explores the 250th anniversary of the nation through the lens of their work. Speakers will be drawn from across Smithsonian museums and research centers, bringing interdisciplinary perspectives and diverse views to celebrate accomplishments and to reflect on the ideals laid out at the founding of the nation – how they have evolved and continue – and what it means to be American today. Beyond a specific date in history, the 250th anniversary offers an opportunity for Smithsonian Affiliates to explore the full breadth of the American story – the people, the moments, the ideals who have made history and affected change in the continually unfolding story of the American experience.
A hearing loop assistive listening system is available for this program to assist guests with hearing loss. Please see our accessibility information for more details.
