He was Professor of Jewish studies at Oxford until his retirement
in 1991, but he continued an active scholarly life right up until
his death.
He'll be remembered mainly for two things, the book "Jesus the Jew",
which sets the gospels in the context of the rabbinical writings
about the time, and argues that Jesus was a hassid, or miracle-
working holy man, of whom there were several in the first century,
and the translation into English of the Dead Sea scrolls.
He did a lot else, of course.
Naturally I don't personally agree with the argument of his first
book. But that doesn't mean that nothing in it is right, or of value,
or of interest.
