I. L. W. V. Jensen (1859-1925)
1926 Obituary 
I. L. W. V. JENSEN was born on the 8th May, 1859, and died on the 5th March, 1925.
He was for many years the chief engineer of the Copenhagen Telephone Co., which he joined in 1882. A man of brilliant parts and exceptional learning acquired by unremitting energy, he quickly rose to a leading position in technical matters. His insight into mathematical physics and his extensive knowledge of materials and their properties, rendered him an undisputed authority on everything appertaining to the construction of apparatus. In respect of electrotechnics and mechanics he was most exacting, his maxim being that the best is not too good. Dr. Jensen's mathematical gifts woo him the highest esteem of mathematicians both at home and abroad, and if he had not devoted himself by preference to telephony he might have made a great name in mathematical history.
He was the recipient of many scientific honours. President of the Mathematical Association, member of the Scientific Society and of various Danish and foreign learned bodies, vice-president of the Danish Electrotechnical Committee, he was Dr. Phil, honoris causa of Lund University. For many years a sufferer from ill-health, he was compelled in 1924 to retire from active work. His name will be associated for all time with the development of technical science in connection with the Copenhagen Telephone Co.
He was elected a Foreign Member of the Institution in 1887 and a Member in 1911. From 1899 until his death he acted as Local Honorary Secretary and Treasurer for Denmark.
