Hogg uses his platform to raise the voices of others who have stood up against violence to create an alliance through their shared loss to end gun violence everywhere. With his younger sister, Lauren, also a student at Marjory Stoneman Douglas High School, he co-wrote “#NeverAgain,” a New York Times bestseller.

The 1918 flu pandemic killed up to 100 million people worldwide in less than a year, disproportionately taking healthy young adults. The personal impact was devastating and wide reaching. This talk draws on stories and newspaper articles to explore the multi-faceted ways the 1918 flu impacted families, sometimes for generations.

Price recently completed a master's degree in history with an emphasis on history of medicine. She loves sharing her passion for social history, genealogy and bringing ancestors to life by placing them in historical and social context.

Historian Joanne B. Freeman of Yale University will recount the long-lost story of physical violence on the floor of the U.S. Congress.

Drawing on a range of sources, she shows that the Capitol was rife with conflict in the decades before the Civil War, when mortal threats, canings, flipped desks and all-out slugfests punctuated legislative sessions. Pistols were drawn and knives brandished in an attempt to intimidate fellow Congressmen into compliance, particularly on the issue of slavery.

Admission is free for members and $10 for non-members.

Art inspired by Walt Kuhn

A new exhibition, “Le Masque and Kuhn’s Metaphors,” an original exhibition and experiment in perception from local artist Alastair Dacey, is being displayed now through Nov. 10 at the French Cultural Center of Boston, 53 Marlborough St.

Inspired by Walt Kuhn’s response to European Modernism in the early 19th century, Dacey spent two years exploring Kuhn’s unique vision and style, seeking to interpret select portraits and use them as guides and catalysts to create wholly new works of art. Recreating the look and feel of each piece posed questions of design, color and form as well as the overarching question of exactness and how literal to be in the details—right down to the feathered caps and embroidery.

The exhibit is free, but reservations are recommended.

Visit www.frenchculturalcenter.org or call 617-912-0400 for more information and to RSVP.
