Well known for his lively decisions and willingness to break with convention, he has had an especially large impact on the interpretation of contracts, shareholder actions in UK company law, in restricting tort liability for public authorities, human rights and intellectual property law, in particular patents.
Born on 8 May 1934, Leonard Hubert Hoffmann was a member of a Jewish family in Muizenberg, South Africa.
His father was a well-known solicitor who co-founded what has become Africa's largest law firm, Edward Nathan Sonnenbergs.

After being called to the Bar from Gray's Inn in 1964, Hoffmann became one of the most sought after and highly priced barristers of his generation and was quickly made a judge, having taken silk on 19 April 1977.
Hoffmann gave the leading judgment in Investors Compensation Scheme Ltd v West Bromwich Building Society, in which he set out five principles for interpreting contracts.
