Carolyn Elizabeth Goodman (née Drucker; 06 October 1915 to 17 August 2007) was an American clinical psychologist who became a prominent civil rights advocate after her son, Andrew Goodman and two other civil rights workers, James Chaney and Michael Schwerner, were murdered by the Ku Klux Klan in Neshoba County, Mississippi, in 1964.
Politically active until age 90, Goodman came to wide public attention again in 2005. Traveling to Philadelphia, Mississippi, she testified at the murder trial of Edgar Ray Killen, a former Klan leader recently indicted in the case. On 21 June 2005, the 41st anniversary of the killings, a jury acquitted Killen of murder but found him guilty of manslaughter in the deaths of Goodman, Chaney, and Schwerner.
Marshall Bertram Rosenberg (06 October 1934 to 07 February 2015) was an American psychologist, mediator, author and teacher.
Starting in the early 1960s he developed Nonviolent Communication, a process for supporting partnership and resolving conflict within people, in relationships, and in society.
He worked worldwide as a peacemaker and in 1984 founded the Center for Nonviolent Communication, an international non-profit organisation for which he served as Director of Educational Services.
