After graduating from the University of Riga, he studied at Jena and the Sorbonne and then emigrated to South Africa, where he joined the giant General Mining company.

Recruited to SOE, he went to Angola. There he arranged the capture of a Vichy ship, sabotaged U-Boat fuel supplies and destroyed Nazi sisal stores. Sent to Portugal and Spain, Manderstam's Memoir he disrupted wolfram supplies to Germany.

He was appointed head of SOE’s Russian section and
led protests against the forcible repatriation of millions of Soviet prisoners.

After the war he built up his own multi-million pounds oil and chemicals consultancy business which is Manderstam International Group.

History of Manderstam International Group

Len Manderstam

This firm of consulting engineers was founded by Mr Manderstam in 1941 commencing active operations in the early 1950s in chemical engineering and in particular soaps, vegetable oils and fats.

After the Second World War Mr. Manderstam continued his high-level contacts with many wartime resistance leaders who subsequently became leading politicians in Africa and south-east Asia. The company retained its links to ex-service personnel and even into the 1980s there were a number of ex-SAS officers working in the firm. Read more about the history of Major Manderstam.

The firm grew along with many other similar firms of consulting engineers such as Eubank & Partners, W. S. Atkins, Binie and Partners, Mott MacDonald all of whom are now major corporate entities either through growth, acquisition or takeover. All these firms were based in and around Victoria Street in London SW1, alongside major contractors such as Humphrey and Glasgow’s, all servicing the major oil companies, also located in Victoria Street.

From the late 60s and into the 1990s Manderstam grew into a substantial firm and
provided detailed engineering services to oil companies and economic feasibility studies to the United Nations, the World Bank and other International Agencies and Governments. Manderstam were the expert witnesses at the Flixborough disaster enquiry and wrote the United Nations Handbook on oil processing which is still used today. In 2008, Manderstam were employed as expert witnesses in the Buncefield explosion in 2005. The BBC has an explanation of the disaster here.

Mr. Manderstam died in 1984 however the business was purchased by the employees and continued as it is today, retaining its unique technical expertise and highly personalised approach to the work undertaken for its clients.
