There were also many examples of empathy and care giving between the groups during these times of illness. Dr. David S. Jones of Harvard University and Dr. Nathaniel Sheidley, director of the Bostonian Society, will talk about both the causes of the epidemics and the human reactions, which were much more nuanced and humane than most people realize.

The exhibition embraces the past and present immigrant communities that have transformed Chinatown. A printmaking installation in the shape of a fan contains over 130 original relief prints from the fifth graders of the Josiah Quincy Elementary School.

Jimenez-Flores is an interdisciplinary artist born and raised is Jalisco, México. He was recently selected to be a 2016-2017 Boston Artist in Residence through Mayor Martin J. Walsh's office.

Hub of literacy

Boston by Foot will offer tours “The Hub of Literacy America” from 10 to 11:30 a.m. on Saturdays during September. Participants will meet at the plaza at School and Washington Streets.

By the 19th century, Boston had earned the nickname “The Athens of America” as an important center for literature and as home to many of the country’s greatest writers. It was the launch pad of American Romanticism, Transcendentalism, the Fireside Poets and American Realism.

This literary tour will highlight the homes and haunts of such prominent writers as Ralph Waldo Emerson, Nathaniel Hawthorne, Henry David Thoreau, Louisa May Alcott, Henry James, Charles Dickens and Henry Wadsworth Longfellow. These great minds gave rise to philosophical discussions that greatly influenced not only their own literary work but also 19th century society at large and our culture today.

Tickets are $15 or $5 for members and can be purchased online in advance or from the guide.
