Nathan Adler was born in 1803 in Hanover, Germany and was the grand-nephew of Chief Rabbi David Tewele Schiff. He was educated at the universities of Gottingen, Erlangen, Wurzburg and Heidelberg and was ordained in 1828. In 1829 he was elected Senior Rabbi of the Grand Duchy of Oldenburg and in 1830 appointed to the office in Hanover in his father's stead. In 1844 Nathan Adler succeeded Chief Rabbi Soloman Hirschell and was installed on the 9th of July 1845.

Nathan Adler worked to establish uniformity of religious practices. In 1847 he issued a code of Laws and Regulations which underlined the supremacy of the Chief Rabbi. He visited provincial congregations and took an active interest in settling or preventing communal disputes. In 1855 he founded Jews College in Finsbury Square, London. It was opened as a school and college, but the attraction of good schools outside the Jewish community and the movement of Jews from the area of the City led to the school being closed in 1879.

Many changes to the composition and administrative framework of Anglo-Jewry took place during this Chief Rabbinate. Important Jewish institutions such as the Jewish Board of Guardians and the Anglo-Jewish Association were founded. In the 1860s Adler encouraged proposals for the union of Ashkenazi congregations under one management and the United Synagogue was created by Act of Parliament in 1870. It was also a period when some Jews examined their approach to their faith; some broke away from traditional observance to worship at the newly formed West London Synagogue, the first Reform congregation in Britain. The number of Jews in the country grew, especially from 1881 with the arrival of thousands of refugees fleeing from pogroms in Russia and Eastern Europe. In 1850 the Jewish population in Britain as around 35,000; in 1914 it stood at 300,000.

In the last decade of his life Nathan Adler had poor health and retired to Brighton. His son Hermann Adler acted for him as Delegate Chief Rabbi until his death on 21st January 1890.
