In 1859, he presided at the first public meeting called in Boston, in regard to the collocation of institutions on the Back Bay lands, where the splendid edifices of the Boston Society of Natural History and the Massachusetts Institute of Technology now stand. Of the latter institution he has been a vice-president, and the chairman of its Society of Arts, and a director from the beginning. General Francis A. Walker, the present president of the Institute, bore this testimony to his efforts in its behalf at the in banquet to Mr. Wilder on his eighty-fifth anniversary: "Through all the early efforts to attract the attention of the legislature and the people to the importance of industrial and art education, and through the severe struggles which so painfully tried the courage and the faith even of those who most strongly and ardently believed in the mission of the Institute, as well as through the happier years of fruition, while the efforts put forth in the days of darkness and despondency were bearing their harvest of success and fame, Colonel Wilder was through all one of the most constant of the members of the government in his attendance; one of the most hopeful in his views of the future of the school; ever a wise counsellor and a steadfast ally."
He was one of the twelve representative men appointed to receive the Prince of Wales in 1860, at the banquet given him in Boston, Edward Everett being chairman of the committee; also one of the commissioners in behalf of the Universal Exposition in Paris, 1867, when he was placed at the head of the committee on horticulture and the cultivation and products of the vine, the report of which was published by act of Congress.
In 1869, he made a trip to the South, for the purpose of examining its resources; and in 1870, with a large party, he visited California. The result of Mr. Wilder's observations has been given to the public in a lecture before the Massachusetts State Board of Agriculture, which was repeated before the Boston Mercantile Library Association, Amherst College, the Massachusetts Agricultural College, Dartmouth College, the Horticultural Society, the merchants of Philadelphia, and bodies in other places.
His published speeches and writings now amount to nearly one hundred in number. A list to the year 1873 is printed in the Cyclopaedia of American Literature. Dartmouth College, as a testimonial to his services in science and literature, conferred upon him, in the year 1877, the degree of Doctor of Philosophy.
The Honorable Paul A. Chadbourne, LL.D., late president of Williams College in a recent Memoir of Mr. Wilder remarks: "The interest which Colonel Wilder has always manifested in the progress of education, as well as the value and felicitous style of his numerous writings, would lead one to infer at once that his varied knowledge and culture are the results of college education. But he is only another illustrious example of the men who, with only small indebtedness to schools, have proved to the world that real men can make themselves known as such without the aid of the college, as we have abundantly learned that the college can never make a man of one who has not in him the elements of noble manhood before he enters its halls."
In 1820, Mr. Wilder married Miss Tryphosa Jewett, daughter of Dr. Stephen Jewett, of Rindge, a lady of great personal attractions. She died on a visit to that town, July 21, 1831, leaving four children. On the twenty-ninth of August, 1833, Mr. Wilder was united to Miss Abigail, daughter of Captain David Baker of Franklin, Massachusetts, a lady of education, accomplishments, and piety, who died of consumption, April 4, 1854, leaving five children. He was married a third time on the eighth of September, 1855, to her sister, Miss Julia Baker, who was admirably qualified to console him and make his dwelling cheerful, and who has two sons, both living. No man has been more blessed in domestic life. We know not where there would be a more pleasing picture of peace and contentment exhibited than is found in this happy family. In all his pursuits and avocations, Mr. Wilder seems to have realized and practised that grand principle, which has such a bearing and influence on the whole course of lifethe philosophy of habit, a power almost omnipotent for good or evil. His leisure hours he devotes to his pen, which already has filled several large volumes with descriptions and delineations of fruits and flowers, proved under his own inspection, and other matters pertaining to his various relations in life.
Colonel Wilder has shown us by his life what an individual may accomplish by industry, perseverance, and the concentration of the intellectual powers on grand objects. Without these, no talent, no mere good fortune could have placed him in the high position he has attained as a public benefactor. He has been pre-eminent in the establishment and development of institutions. Few gentlemen have been called upon so often, and upon such various occasions, to take the chair at public meetings or preside over constituted societies. Few have acquitted themselves so happily, whether dignity of presence, amenity of address, fluency of speech, or dispatch of business, be taken into consideration. As a presiding officer he seems "to the manner born." His personal influence has been able to magnetize a half-dying body into new and active life. This strong personal characteristic is especially remarked among his friends. No one can approach him in doubt, in despondency, or in embarrassment, and leave him without a higher hope, a stronger courage, and a manlier faith in himself. The energy which has impelled him to labor still exists.
Mr. Wilder is now president of the New England Historic Genealogical and Society, the American Pomological Society, and the Massachusetts Agricultural Club. He is senior trustee of the Massachusetts Agricultural College, and senior member of the State Board of Agriculture, and of the executive committee of the Massachusetts Horticultural Society. He is senior director in the Massachusetts Institute of Technology, the Hamilton National Bank, the New England Mutual Life Insurance Company, and the Home Savings Bank. He is an honorary member of the Royal Historical Society of Great Britain; a corresponding member of the Royal Horticultural Society of London, and the Société Centrale d' Horticulture of France; and a fellow of the Reale Accademia Araldica Italiana of Pisa.
Well did Governor Bullock on a public occasion speak of Mr. Wilder as "one who has applied the results of his well-earned commercial earnings so liberally that in every household and at every fireside in America, when the golden fruits of summer and autumn gladden the sideboard and the hearthstone, his name, his generosity, and his labors are known and honored." He is also known and honored abroad. The London Gardener's Chronicle, the leading agricultural paper in Europe, in April, 1872, gave his portrait and a sketch of his life, in which is introduced the following merited compliment:
"We are glad to have the opportunity of laying before our readers the portrait of one of the most distinguished of transatlantic horticulturists, and one who, by his zeal, industry, and determination, has not only conferred lasting benefits on his native country, but has by his careful experiments in hybridization and fruit-culture laid the horticulturists of all nations under heavy obligations to him. The name and reputation of Marshall P. Wilder is as highly esteemed in Great Britain as they are in America."
In closing this sketch, we may remark that complimentary banquets were given him on the eightieth and the eighty-fifth anniversaries of his birth. On the former occasion, September 22, 1878, the Reverend James H. Means, D.D., his pastor for nearly thirty years, the Honorable Charles L. Flint, secretary of the Board of Agriculture, the Honorable John Phelps Putnam, judge of the Massachusetts Superior Court, and others, paid tributes to the high moral character, the benevolent disposition, and the eminent services, of the honored guest of the evening.
