Puleo will talk about the Great Molasses Flood on the centennial anniversary of the tragedy that occurred in Boston’s North End when a 50-foot steel tank with 2.3 million gallons of molasses collapsed on the waterfront. A wave of molasses traveling at 35 miles per hour killed 21 and injured 150 people. Puleo will talk about this event that has become part of local folklore and the resulting landmark court battles that changed laws and regulations regarding construction.

Puleo is a historian, educator and the author of six best-selling narrative nonfiction books, including “Dark Tide: The Great Molasses Flood of 1919.”

Erasure of African identity

The Massachusetts Historical Society, 1154 Boylston St., will present “Race, Empire and the Erasure of African Identities in Harvard’s National Skulls” from 6 to 7:30 p.m. on Thursday, Jan. 17. There will be a pre-talk reception at 5:15 p.m.

Christopher Willoughby, Schomburg Center for Research in Black Culture, will present this program, with comment by Evelynn Hammonds of Harvard University.

In 1847, John Collins Warren gave his anatomical collection to the Harvard medical school, including a collection of “national skulls.” This paper analyzes how skulls from the black Atlantic were collected and dubbed “African,” to show that medical schools were intimately connected to the violence of slavery and empire, and to posit a method for writing the history of racist museum exhibitions that does not continue the silencing of black voices at the heart of those exhibitions.
