Erwin Hermann Lambert (7 December 1909 — 15 October 1976) was a perpetrator of the Holocaust. In profession, he was a master mason, building trades foreman, Nazi Party member and member of the Schutzstaffel with the rank of SS-Unterscharführer (Corporal). He supervised construction of the gas chambers for the Action T4 euthanasia program at Hartheim, Sonnenstein, Bernburg and Hadamar, and then at Sobibor and Treblinka extermination camps during Operation Reinhard. He specialized in building larger gas chambers that killed more people than previous efforts in the extermination program.

Lambert was born on 7 December 1909 in Schildow, a small town in Mühlenbecker Land, in the Niederbarnim district. His father was killed in the First World War; his stepfather owned a construction firm in Schildow. After basic schooling, Lambert became an apprentice, first to a locksmith, and then to a mason. After passing his apprentice exam, he attended a school for the building trades in Berlin in the mid-1920s and passed his examination for master mason in the mid-1930s. He was always employed, working as a mason and, after becoming a master mason, as a foreman for various Berlin construction firms.

Muhammad Ali (born Cassius Marcellus Clay, Jr.; January 17, 1942) is an American former professional boxer, philanthropist and social activist. Considered a cultural icon, Ali was both idolized and vilified.

Originally known as Cassius Clay, Ali changed his name after joining the Nation of Islam in 1964, subsequently converting to Sunni Islam in 1975, and more recently practicing Sufism.^{[clarification needed]} In 1967, three years after Ali had won the World Heavyweight Championship, he was publicly vilified for his refusal to be conscripted into the U.S. military, based on his religious beliefs and opposition to the Vietnam War. Ali stated, "I ain't got no quarrel with them Viet Cong... No Viet Cong ever called me nigger" – one of the more telling remarks of the era.

Widespread protests against the Vietnam War had not yet begun, but with that one phrase, Ali articulated the reason to oppose the war for a generation of young Americans, and his words served as a touchstone for the racial and antiwar upheavals that would rock the 1960s. Ali's example inspired Martin Luther King Jr. – who had been reluctant to alienate the Johnson Administration and its support of the civil rights agenda – to voice his own opposition to the war for the first time.
