Mary Donaldson, Baroness Donaldson of Lymington Mary Donaldson, Baroness Donaldson of Lymington Dorothy Mary Donaldson, The Lady Donaldson of Lymington, (née Warwick, 29 August 1921 – 4 October 2003), previously known as Dame Mary Donaldson, was the first female Lord Mayor of London (1983–84). Born at Wickham, Hampshire, the daughter of an ironmonger and a school teacher, Donaldson trained as a nurse during the war and qualified in 1946. From 1967–69, she chaired the Women's National Cancer Control Campaign, and then the Vice President of the British Cancer Council. In 1966, she was elected a Member of the City of London Court of Common Council, and
Simon Donaldson first results gave severe restrictions on the intersection form of a smooth four-manifold. As a consequence, a large class of the topological four-manifolds do not admit any smooth structure at all. Donaldson also derived polynomial invariants from gauge theory. These were new topological invariants sensitive to the underlying smooth structure of the four-manifold. They made it possible to deduce the existence of "exotic" smooth structures—certain topological four-manifolds could carry an infinite family of different smooth structures. After gaining his DPhil degree from Oxford University in 1983, Donaldson was appointed a Junior Research Fellow at All Souls College, Oxford, he spent
