Slain public servants

'Better Angels: Firefighters of 9/11,' by Dawn Howkinson Siebel, at the Wood Museum, Springfield, Mass through July 10.

Her work features 343 portraits, one for every New York City firefighter lost in the attacks on the World Trade Center. The images are along a 21-foot-long wall, allowing visitors to come face to face with men who made a living out of risking their own in order to save others.
