There have been two sets of father and son Chief Rabbis: Hart Lyon and Solomon Hirschell, and Nathan Adler and Hermann Adler.
Except for Rabbi Hart Lyon until Sir Israel Brodie all Chief Rabbis served until their deaths and therefore the year of end of office also indicates year of death. Rabbi Hart Lyon died in 1800 and Sir Israel Brodie in 1979. Lord Jakobovits retired in 1991 and died in 1999.
Most Chief Rabbis were aged between 35 and 46 on their appointment.
Seven served 20 years or more, and of these three were in office for 40 years or more.
The longest period was served by Aaron Hart, appointed at the age of 39 he served for 46 years. The longevity of post holders has provided stability to Anglo Jewry.
During the 290 years the longest gap between two Chief Rabbis was the 10 years between Rabbi David Tevelle Schiff’s death and Rabbi Solomon Herschell’s appointment.
