In his youth, Landmann was awarded a grant to study leather manufacture at the Northampton College of Technology before joining Lankro chemicals, where he learned to make, test and control leather finishes. He continued his studies to obtain an honours degree in chemistry and became an Associate of the Royal Society of Chemistry and, later, a Fellow. Axel Landmann joined the British Leather Manufacturers Research Association (BLMRA) (later to become the BLC Leather Technology Centre), where he remained for the rest of his career until retirement. There he started a new department of Leather Finishing and also guided the research with a strong emphasis on practical applications, including the evaluation and development of test methods.

He represented a variety of committees, including SLTC and IULTCS. Axel Landmann also lectured at congresses of the Hungarian and Czechoslovak Leather Societies. He served a term as SLTC President and remained a member of the committee during his retirement. He was an advisor to the Ministry of Defence on leather methods and appeared as an expert witness in court on behalf of the Trading Standards Department in case of leather descriptions and performance.

Four years ago, the SLTC established an annual award in his name, the Axel Landmann certificate, given annually to a person that has made an outstanding contribution to the promotion of the leather industry.

He will be greatly missed by those who knew him for his sense of humour, amazing intellect and deep knowledge and love of leather science and technology.
