Aaron Adolph Saphir (26 September 1831 – 4 April 1891) was a Hungarian Jew who converted to Christianity and became a Jewish Presbyterian missionary.

[4][5] In the autumn of 1843 his father sent him to train as a Christian minister for the Free Church of Scotland at New College, Edinburgh.

As he was not quite able to undertake all of the duties of the pastorate, a generous donor provided money to pay an assistant minister.

Dr. Saphir died of angina pectoris on 3 April 1891, just three days after the death of his wife on 31 March.

[10] Adolph Saphir's siblings were also involved in the Hebrew Christian movement and missionary activities: Philipp, whose letters and diaries Adolph edited, ran a mission school in Budapest;[11] Johanna taught at the school and later married Charles Andrew Schönberger, co-founder of the Hebrew Christian Testimony to Israel;[12] and Maria Dorothea married the noted Hebrew Christian preacher Carl Schwartz.
