David Johnston - 1954-2001 (p.13)

This is the full text of the obituary by David Hood.

David Johnston graduated from Queen's with a PhD in 1980. He had previously been awarded B.Sc. 2.1 Honours degree in Geology at QUB and had attended the Royal Belfast Academical Institution. He was also a Queen's Scout and had gained a Gold Duke of Edinburgh award.

From Queen's he went on to a Post-Doctoral Fellowship at Imperial College and then took up a post with BP Research at Sunbury where he managed the Electron Microscopy Department. He left BP in 1993 but in his later years was unable to realise the career in geology for which he had been so well trained.

Those who were at Queens between 1972-1980 will remember him with great affection. He was easily recognised with his curly fair hair and beard even though he was quite short in stature. He was known as 'wee-legs' - a nickname he was given by his friends in the 74th Belfast Venture Scouts (whom he helped found) and this nickname stuck throughout his time at QUB.

Dave had many admirable characteristics. He was a kind person and befriended many younger geology undergraduates as they came 'through the ranks'. He also took much time to discuss problems with his peers and was a keen debater of current issues. He could always be found for advice either in the department or very often in the Union coffee bar reading his beloved Daily Mail - pouring over the crossword or the Fred Bassett cartoon. He also had an impish sense of humour but this was always delivered in good fun and was never malicious. He was often 'found out' playing practical jokes on his peers. However, he did not stand fools lightly and lambasted people who went 'too far' on QUB Geological Society weekend trips. He detested wasting time and would always be one of the first to 'get going' on field trips, invariably driving one of the transit vans.

He had an enviable style in note-taking and many of his peers were in constant debt to him if they missed any of the memorable Saturday morning geology lectures given by 'Bogey', Ken or 'Basher'.

He was also a keen five-a-side soccer player and a member of the infamous 'John Bridge select five'.

During our undergraduate days we spent much time on field trips either as part of the B.Sc. degree course or on QUB Geol. Soc. weekend 'bashes'. I recall two trips very clearly.

On a first year undergraduate Geography Department course to Arran we were both determined to do as little geography as possible and saw the trip as an opportunity to push the boundaries of 'physical geography' to the extreme. Somehow we were asked to map the geology of the famous Corrie shoreline in northeast Arran - possibly Dave's first real geology mapping project. During his final presentation Dave took his impish humour to great heights by rhyming off a well rehearsed list of Goniatite names, as if he had studied them all his life - a truly jaw-dropping experience for his fellow geography students.

On another trip around Easter 1974 in our second year, Dave, Brian Turnage and myself spent a glorious week on the Rosguill peninsula in north Donegal, mapping out the complex pelites, migmatites and associated structures. That week is etched on my memory - the weather was incredible, the scenery spectacular and the 'crack' and music terrific. We all returned to Belfast very bronzed having experienced one of the hottest April's on record in Ireland.

Dave 'shone' in the field and went on to complete a high class mapping project in north Donegal during his Honours year. Around this time he developed a great passion for garnets and this progressed into a superb research project and PhD thesis on garnets from the northern Alps - supervised by Ken Jones.

Dave was a very methodical, gifted and talented individual. Those of us who had the privilege to know him are deeply saddened by his untimely death. Dave is survived by Anne who he married in 1982 and by his daughter Kate (born 1984).

Apology

On p.14, the picture of the book cover illustration of The North of Ireland by Paul Lyle, for some inexplicable reason, didn't come out in the final printing. Apologies to Paul. His very striking image of the Giant's Causeway will appear in Issue 8. By then, of course, many readers will probably have seen it on their own copy!
