Donald Thomas "Tom" Scholz - photo right - (born March 10, 1947), is an American rock musician, songwriter, guitarist, inventor, and electronics engineer. He is best known as the founder of the hard rock band Boston and inventor of the Rockman guitar amplifier. Scholz, as noted by All Music Guide, is "a notoriously 'un-rock n' roll' figure who never enjoyed the limelight of being a performer," but instead concentrated on his music. After achieving commercial success with Boston, Scholz has spent much of his time working with charities.

from wikipedia [undated but appears to have been wriitten in 2007] :
Scholz, a vegetarian for 29 years, has been a supporter of many organizations including PETA and Greenpeace. He set up his own charitable foundation, the DTS Charitable Foundation, in 1987 to help support such causes as animal protection, providing vegetarian resources, stopping world hunger, creating homeless shelters, food banks, as well as animal rescues and sanctuaries, and advocating for children's rights. Through his work with his foundation he has raised millions of dollars.
Delp . . . had been a vegetarian for over thirty years and had contributed to a number of charitable causes.
from bandboston.com [the official website, also undated]:
Tom has been a vegetarian for over 25 years, and supports many ethical organizations with a foundation that he set up in 1987 to help animal protection, world hunger and the homeless. To date, his charitable foundation has donated several million dollars to those causes. He received the Mahatma Ghandi Award in 1987 and was named Man of the Year by the National Hospice Organization in 1988. A knee injury ended 35 years of competitive basketball, so now Tom enjoys freestyle skating, "extreme croquet," and piloting his single-engine plane around the U.S in his leisure time.
A vegetarian for 38 years, Brad was a compassionate soul who dedicated time and money for various charitable causes that were dear to his heart.
Gary Pihl - A long-time vegetarian like Brad and Tom.
The above suggests that Brad became vegetarian in 1969, and Tom followed in the late 70s.
