One who had exceptional opportunities of knowing him wrote: “His characteristic of intensity in whatever he was engaged in was remarkable. Even in his relaxations he entered into them with his whole heart; indeed, it did one good to hear his ringing laugh when witnessing some amusing play—the face lit up with well-nigh childlike pleasure—no trace of the weariness which had been visible after a long day of work of such varied kinds, all demanding his most serious attention, involving often momentous world-wide results. As a travelling companion he was indeed the light and happiness of those who had the privilege to be with him. Everything that could lessen fatigue, or add to the enjoyment and interest of the journey, was thought of, and tenderly carried out, and the knowledge of the pleasure he was giving was his sweet reward. Young people and children clustered round him, and he spared no trouble to explain simply and clearly any question they asked him.” The Rev. D. Fraser, in a funeral address, said: “The combination of mental power with moral uprightness and strength is always impressive. And this is what signally characterised him whose death we mourn. There have been very few more active and inquiring minds in this generation: the keenness and swiftness of his intellectual processes were even more surprising than the extent and variety of his scientific attainments. But such powers and such acquirements have, alas! been sometimes in unworthy alliance with jealous dispositions and a low moral tone. What will endear to us the memory of William Siemens is that he was, while so able and skilful, also so modest, so upright, so generous, and so totally free from all narrowness and paltriness of spirit. And God, whose wisdom and power he reverently owned, has taken him from us!”
