The Salle Centrale was engaged for three days, August 30th to September 2nd of the next year, 1927. Back I went to London to enlist an English committee. Clinton Chance became my husband’s assistant in supervising finances, and also provided London headquarters in his offices, supplying stenographers and secretaries. Edith How-Martyn joined us and I secured the invaluable aid of Julian Huxley, brother of Aldous, a brilliant, young, enthusiastic scientist, alive and having a mind that not only took things in, but gave them out. The Conference owed much to his fair and just opinions and the fine supporters he rounded up. Together we went over names and names and names, trying to choose a chairman of sufficient distinction around whom European scientists would rally. Professor A. M. Carr-Saunders at first accepted, but a month and a half later informed me his other obligations were so heavy he would have to limit his participation to membership on the Council. After weeks of uncertainty, interviews, and rejections, we selected Sir Bernard Mallet, K.C.B., once of the Foreign Office, Treasury, Board of Inland Revenue, later Registrar General of Births, Deaths, and Marriages, and President of the Royal Statistical Society. Although very English, he was not too conservative. He knew well Sir Eric Drummond, then head of the League of Nations, and also had many friends on the Continent, particularly in Italy. He was typical of an individual who had climbed far, who knew where he was going and the road by which he should travel. Bored at being now in retirement, he accepted our offer willingly because, although no salary was attached, it would give him a position and an interest, and keep him socially in touch with noteworthy figures. Lady Mallet’s previous experience as lady-in-waiting to Queen Victoria made her an expert hostess, and this too we needed. Once I had to make an expedition all the way to Edinburgh to seek out Dr. F. A. E. Crew, a shining light among the younger biologists, who was making hens crow and roosters lay eggs. He readily agreed to come to the Conference and during the two days I visited him helped me build up my program.
