I regard the independent metallic frame for holding the strings of pianos as an invention which would do honor to any professional mechanician; and I contemplate with much satisfaction the circumstance that my departed friend intrusted to me the construction of the first specimen of his important improvement.
I am, my dear Mrs. Bull, Yours very sincerely, J. ERICSSON.
Mr. Ericsson had previously written of Ole Bull: “So warm a heart and so generous a disposition as his I have never known.” These words, it may be truthfully said, express the sentiment and the judgment of the violinist concerning the great engineer and inventor.
Professor H. Helmholtz, whose works on tone Ole Bull had carefully studied, says of the violinist in a letter written in May, 1881:—
I saw that he was thoroughly well informed as to the mechanical problems concerning the violin, which came in question.... I was much impressed by his personal character; he was at the same time so enthusiastic and so intelligent, interested in all the great problems of humanity.
The pleasantest incident of his concert tour in the season of 1871–72 was a visit he made to his friend, Mr. William H. Seward, in Auburn, N. Y. The two delightful days spent at Mr. Seward’s house relieved the tedium of the whole trip.
The summer of 1872 he was in Norway, and in the fall returned again to the United States, giving some seventy–five concerts, with his usual success, during the winter. The last concerts announced were given up, on account of the illness of his infant daughter.
In the spring he returned to Norway, and occupied for the first time the new house which had been built at Lysö during his absence. The winter following was mostly passed in Southern France. While on a visit to Florence, he met again his old friend Prince Poniatowsky, and also many others whom he had known nearly forty years before, when he had been made an honorary member of the Philharmonic Society of that city. Professor Sbolczis urged Ole Bull to permit his friends to hear him, offering the aid of his own orchestra; and not only the importunity of his friends, but the thought of again trying his power over such an audience as the city of the Arno can offer, tempted him to play. The hall was crowded, the tickets having been taken by storm, and the performers suffered considerable inconvenience therefrom. But to this an Italian readily accommodates himself under such circumstances.
