Hermann Ludwig Maas (German: [ˈhɛʁ.man ˈmaːs] ⓘ; 5 August 1877 – 27 September 1970) was a Protestant minister, a doctor of theology and named one of the Righteous Among the Nations,[1] a title given by the Israeli organization for study and remembrance of the Holocaust - Yad Vashem, for people who helped save the lives of Jews during the Holocaust without seeking to gain thereby.
Maas, who had decidedly liberal and pacifist views, caused a scandal in 1925 by attending the funeral of social democratic Reichspräsident Friedrich Ebert.
In 1933, when the Nazi regime introduced the economic boycott of the Jews of Germany, Maas first went to Palestine to meet with some of the Zionist activists, impressing them by speaking fluent Hebrew.
After Hitler's Machtergreifung ("seizure of power") he joined the Pfarrernotbund and the Confessing Church along with other notable Protestant theologians such as Dietrich Bonhoeffer, Martin Niemöller and Hans Ehrenberg.
A street in Rehovot (in the eastern suburb of Qiryat HaYovel) is named after him and a grove inside "Orde Wingate Forest" at Mount Gilboa.
