In spite of all emphasis on objectivity, a scientific discipline needs for its development outstanding research workers with exceptional personal qualities. A scientist with these qualities is honoured here, on the occasion of his 70th birthday, by his pupils, friends and colleagues: Arthur Linder is respected as a researcher, advisor and teacher in the field of Applied Statistics. Professor Dr. Dr. h. c. A. Linder has demonstrated the utility of statistical methods in science and technology; these are recognised today as being essen tial for an objective evaluation of data. His contacts with Sir R. A. Fisher, C. 1. Bliss, G. M. Cox, W. G. Cochran, P. C. Mahalanobis and many other ex perts, have helped him to achieve his almost legendary authority on sampling and on the evaluation of statistical data. Linder has won many friends and adherents to the cause of Biometry, Econometry and Technometry, firstly through his teaching activity at the universities of Berne, Geneva and Lausanne and the Swiss Federal Institute of Technology in Zurich, and as visiting lecturer at the Indian Statistical Institute, the International Statistical Education Centre in Calcutta, the Uni versity of North Carolina and the University of Natal in Durban, secondly through his contributions to the literature as author of the monographs 'Sta tistische Methoden' and 'Planen und Auswerten von Versuchen', as editor of METRIKA and co-editor of other journals, and thirdly through his active collaboration in the founding of The Biometric Society, to the presidency of
