The US State Department official Francis Bowes Sayre Sr. was his brother.

Sayre taught nonviolent techniques at the Brookwood Labor College.

Hiss Case
Whittaker Chambers's wife Esther Shemitz and her friend Grace Lumpkin worked for Sayre on the staff of The World Tomorrow magazine during the 1920s.

Later, Sayre's brother Francis Bowes Sayre Sr. had Alger Hiss reporting to him at the State Department, then declined to testify on Hiss's behalf.
