NURTURED by Christianity but moulded in the school of hard knocks, Andrew Lochhead, who has died at the age of 90, was one of Scotland's grander sons, a monument to first-world concern for third-world poverty.

At 65, an age when so many people put their feet up, this quite extraordinary son of a Scottish Presbyterian minister and American mother of Dutch ancestry, became a founding father of the Centre for

Development Studies which remains an internationally recognised institution in its field to help the Third World change itself by thinking ahead and planning scientifically.

Change was the key word during the long life of Andrew Van Slyke Lochhead who

was born in Montreal three years before a war which

so dramatically altered the

way wealthy nations and

affluent and educated individuals within those developed nations viewed the world

and their own responsibilities

within it.

After his family returned

to Britain,Lochhead attended

the famous Bedales School. He was very much attracted to

the ideals of social service

and self-sacrifice promoted within the school. Throughout his long life, the Christian

ethic remained a force and constant prodder.

After school came a period of travel, mainly in France (which he loved) and Germany, which he feared. For this was Germany during the Weimar Republic when strange and disturbing forces battled to control the minds of men.

It was in Paris that the young Andrew Lochhead first encountered one of the most extraordinary Scots of the twentieth century, Patrick Geddes who went on to become the founder of the town planning movement. Geddes (later Sir Patrick) was a Scottish ''renaissance man'' who contributed much to the fields of ecology and philosophy.

Aware that his own changing assumptions (the theme of his 1999 memoirs) would be sharpened by the power of education. He applied for and won a scholarship to St John's College, Oxford, where he undertook vacation work in the east end of London with the Oxford and Bermondsey clubs.

It was a period of his life that brought home the crippling effects of poverty.

Watching it breed and spread at home made him acutely are of its international repercussions. In places such as Bethnal Green and Dalston he befriended a number of Africans and Indians who

were later to make such indelible marks in their own post-imperial states.

Like a kindred spirit from the same age, George Orwell, middle-class ''Lockheed'' dressed up poor to win his way into the hearts of ordinary Londoners. But his accent always gave him away. He realised (as did the author of Down and out in London and Paris) that to fudge your class origins while on a war to change the class system was mildly ridiculous.

When the Second World War came, Lochhead volunteered for the Royal Navy. Lochhead served with distinction in Arctic waters. In December 1942 he took part in the Battle of

the Barents Sea and ended

the war with the rank of

lieutenant-commander.

The war refined his growing sense that society needed

to organise itself if it were

to defeat poverty and he

gained valuable experience as an urban administrator when he became general secretary

of the Bristol Council for Social Service.

In 1952, he was made a

tutor in social science and social work at University College, Cardiff, and there

he became immersed in

social development in low-income countries. In 1953,

he and the distinguished Robin Huws Jones designed a course for African students known

as the United Nations Course, since the world body provided both the course's finance

and students.

After distinguishing himself as an administrator and planner at Swansea University in the 1960s, Lochhead pioneered the UK's first masters degree in social planning specifically designed to meet the needs of developing countries.

With close connections to the British Council, the Overseas Development Ministry, and several NGOs, he spent 1969-1970 at the University of Khartoum and, as a result

of work there, he was awarded an OBE.

As he grew older, Andrew Lochhead kept up a tiring

travel schedule, which kept him face to face with the reality of third-world poverty.

As well as sharing his vast knowledge and experience with trainers in the developed world, he generously passed it all on to promising young politicians in the Third World, one of them Thabo Mbeki, today's South African president.

Lochhead was blessed with a long and happy marriage, He tied the knot with Sheila

MacDonald in 1948. She was one of the six children of Ramsay MacDonald, the first Labour prime minister.

The couple are survived by

a son and two daughters.
