But the people did not doubt. There was a rush from all over Europe to Copenhagen. Its streets became filled with men and women whose faces were shrouded in heavy bandages, and it was easy to tell the new-comers from those who had seen “the professor.” They came in gloom and misery; they went away carrying in their faces the sunshine that gave them back their life. Finsen never tired, when showing friends over his Institute, of pointing out the joyous happiness of his patients. It was his reward. For not “science for science’s sake,” or pride in his achievement, was his aim and thought, but just the wish to do good where he could. Then, in three more years, they awarded him the great Nobel prize for signal service to humanity, and criticism was silenced. All the world applauded.
“They gave it to me this year,” said Finsen, with his sad little smile, “because they knew that next year it would have been too late.” And he prophesied truly. He died nine months later.
All that is here set down seems simple enough. But it was achieved with infinite toil and patience, by the most painstaking experiments, many times repeated to make sure. In his method of working Finsen was eminently conservative and thorough. Nothing “happened” with him. There was ever behind his doings a definite purpose for which he sought a way, and the higher the obstacles piled up the more resolutely he set his teeth and kept right on. “The thing is not in itself so difficult,” he said, when making ready for his war upon the wolf, “but the road is long and the experiments many before we find the right way.”
He took no new step before he had planted his foot firmly in the one that went before; but once he knew where he stood, he did not hesitate to question any scientific dogma that opposed him, always in his own quiet way, backed by irrefutable facts. In a remarkable degree he had the faculty of getting down through the husk to the core of things, but he rejected nothing untried. The little thing in hand, he ever insisted, if faithfully done might hold the key to the whole problem; only let it be done now to get the matter settled.
Whatever his mind touched it made perfectly clear, if it was not so already. As a teacher of anatomy he invented a dissecting knife that was an improvement on those in use, and clamps for securing the edges of a wound in an operation. As a rifle shot he made an improved breech; as a physician, observing the progress of his own disease, an effective blood powder for anaemia. At the Light Institute, which friends built for him, and the government endowed, he devised the powerful electric lamps to which he turned in the treatment of lupus, for the sun does not shine every day in Copenhagen; and when it did not, the lenses that gathered the blue rays and concentrated them upon the swollen faces were idle. And gradually he increased their power, checking the heat rays that would slip through and threatened to scorch the patient’s skin, by cunning devices of cooling streams trickling through the tubes and the hollow lenses.
Nothing was patented; it was all given freely to the world. The decision which he and his wife made together was made once for all. When the great Nobel prize was given to him he turned it over to the Light Institute, and was with difficulty persuaded to keep half of it for himself only when friends raised an equal amount and presented it to the Institute.
Finsen knew that his discoveries were but the first groping steps upon a new road that stretched farther ahead than any man now living can see. He was content to have broken the way. His faith was unshaken in the ultimate treatment of the whole organism under electric light that, by concentrating the chemical rays, would impart to the body their life-giving power. He himself was beyond their help. Daily he felt life slipping from him, but no word of complaint passed his lips. He prescribed for himself a treatment that, if anything, was worse than the disease. Only a man of iron will could have carried it through.
A set of scales stood on the table before him, and for years he weighed every mouthful of food he ate. He suffered tortures from thirst because he would allow no fluid to pass his lips, on account of his tendency to dropsy. Through it all he cheerfully kept up his labors, rejoicing that he was allowed to do so much. His courage was indomitable; his optimism under it all unwavering. His favorite contention was that there is nothing in the world that is not good for something, except war. That he hated, and his satire on the militarism of Europe as its supreme folly was sharp and biting.
Of such quality was this extraordinary man of whom half the world was talking while the fewest, even in his own home city, ever saw him. Fewer still knew him well. It suited his temper and native modesty, as it did the state of his bodily health, to keep himself secluded. His motto was: “bene vixit qui bene latuit—he has lived well who has kept himself well hidden”—and his contention was always that in proportion as one could keep himself in the background his cause prospered, if it was a good cause. When kings and queens came visiting, he could not always keep in hiding, though he often tried. On one of his days of extreme prostration the dowager empress of Russia knocked vainly at his door. She pleaded so hard to be allowed to see Dr. Finsen that they relented at last, and she sat by his bed and wept in sympathy with his sufferings, while he with his brave smile on lips that would twitch with pain did his best to comfort her. She and Queen Alexandra, both daughters of King Christian, carried the gospel of hope and healing from his study to their own lands, and Light Institutes sprang up all over Europe.
In his own life he treated nearly nineteen hundred sufferers, two-thirds of them lupus patients, and scarce a handful went from his door unhelped. When his work was done he fell asleep with a smile upon his lips, and the “universal judgment was one of universal thanksgiving that he had lived.” He was forty-three years old.
