The fame of Sir William Siemens was world-wide, as it deserved to be; but those who knew him best will be the most ready to acknowledge that the qualities of his heart were no less conspicuous than those of his intellect. Hear what his pupils and assistants said of him:—“How my dear old master will be missed, and what a gap in many walks of life will be unfilled!” “There are many younger members of our profession who will look elsewhere in vain for such genial uniform kindness and sympathy as his invariably was.”“The seven years I spent in his service were the happiest in my life.” “It was the loss of the kindest and best friend I ever had, and I have not known such sorrow since the loss of my older brother. The keenest incentive I had in my new work was the desire of showing him that his kindly recommendation was justified by the event.”In acknowledging the gift from Lady Siemens of some objects of remembrance, one writes: “They, as visible objects on which his eyes must have rested frequently, will, I feel certain, when I shall look at them, tend to encourage me in overcoming difficulties, of which there exist always plenty for those who wish to contribute their share, however small, to the progress of things of this world. It is this example which Sir William Siemens has given to all the world, which will, I believe, be the most beneficial for future generations, and for those who are wise enough to follow it.” Of his character as a man of business let Messrs. Chance Bros. speak, as one testimony out of many: “Our firm having been the first to carry out in England on a large scale the Siemens regenerative process, we were brought into close and frequent communication with him, and had the opportunity of appreciating not only his extraordinary inventive powers, but also his thorough straightforwardness and integrity of character.” I have spoken of his interest in education, and I quote two opinions thereon. Lord Sherbrooke, in conversation with a mutual friend, regretted immensely that he had not been a pupil of Sir W. Siemens, and spoke of him, and of those who were working with him to enlarge our sphere of knowledge, as the salt of the earth. A distinguished American expressed himself as strongly impressed not only with a sense of his great learning, but with admiration of the native strength of his mind, and the soundness of his educational views.
