It is generally stated that the influence of Maria White made Lowell an Abolitionist, but this is only qualifiedly true. A year before he had met her he wrote to a friend: "The Abolitionists are the only ones with whom I sympathize of the present extant parties." Freedom, justice, humanitarianism were fundamental to his native idealism. Maria White's enthusiasm and devotion to the cause served to crystallize his sentiments and to stimulate him to a practical participation in the movement. Both wrote for the Liberty Bell, an annual published in the interests of the anti-slavery agitation. Immediately after their marriage they went to Philadelphia where Lowell for a time was an editorial writer for the Pennsylvania Freeman, an anti-slavery journal once edited by Whittier. During the next six years he was a regular contributor to the Anti-Slavery Standard, published in New York. In all of this prose writing Lowell exhibited the ardent spirit of the reformer, although he never adopted the extreme views of Garrison and others of the ultra-radical wing of the party.
But Lowell's greatest contribution to the anti-slavery cause was the Biglow Papers, a series of satirical poems in the Yankee dialect, aimed at the politicians who were responsible for the Mexican War, a war undertaken, as he believed, in the interests of the Southern slaveholders. Hitherto the Abolitionists had been regarded with contempt by the conservative, complacent advocates of peace and "compromise," and to join them was essentially to lose caste in the best society. But now a laughing prophet had arisen whose tongue was tipped with fire. The Biglow Papers was an unexpected blow to the slave power. Never before had humor been used directly as a weapon in political warfare. Soon the whole country was ringing with the homely phrases of Hosea Biglow's satiric humor, and deriding conservatism began to change countenance. "No speech, no plea, no appeal," says George William Curtis, "was comparable in popular and permanent effect with this pitiless tempest of fire and hail, in the form of wit, argument, satire, knowledge, insight, learning, common-sense, and patriotism. It was humor of the purest strain, but humor in deadly earnest." As an embodiment of the elemental Yankee character and speech it is a classic of final authority. Says Curtis, "Burns did not give to the Scotch tongue a nobler immortality than Lowell gave to the dialect of New England."
The year 1848 was one of remarkably productive results for Lowell. Besides the Biglow Papers and some forty magazine articles and poems, he published a third collection of Poems, the Vision of Sir Launfal, and the Fable for Critics. The various phases of his composite genius were nearly all represented in these volumes. The Fable was a good-natured satire upon his fellow authors, in which he touched up in rollicking rhymed couplets the merits and weaknesses of each, not omitting himself, with witty characterization and acute critical judgment; and it is still read for its delicious humor and sterling criticism. For example, the lines on Poe will always be quoted:
"There comes Poe, with his raven, like Barnaby Rudge,
Three-fifths of him genius and two-fifths sheer fudge."
And so the sketch of Hawthorne:
"There is Hawthorne, with genius so shrinking and rare
That you hardly at first see the strength that is there;
A frame so robust, with a nature so sweet,
So earnest, so graceful, so lithe and so fleet,
Is worth a descent from Olympus to meet."
Lowell was now living in happy content at Elmwood. His father, whom he once speaks of as a "Dr. Primrose in the comparative degree," had lost a large portion of his property, and literary journals in those days sent very small checks to young authors. So humble frugality was an attendant upon the high thinking of the poet couple, but this did not matter, since the richest objects of their ideal world could be had without price. But clouds suddenly gathered over their beautiful lives. Four children were born, three of whom died in infancy. Lowell's deep and lasting grief for his first-born is tenderly recorded in the poems She Came and Went and the First Snow-Fall. The volume of poems published in 1848 was "reverently dedicated" to the memory of "our little Blanche," and in the introductory poem addressed "To M.W.L." he poured forth his sorrow like a libation of tears:
"I thought our love at fall, but I did err;
Joy's wreath drooped o'er mine eyes: I could not see
That sorrow in our happy world must be
Love's deepest spokesman and interpreter."
The year 1851–52 was spent abroad for the benefit of Mrs. Lowell's health, which was now precarious. At Rome their little son Walter died, and one year after their return to Elmwood sorrow's crown of sorrow came to the poet in the death of Mrs. Lowell, October, 1853. For years after the dear old home was to him The Dead House, as he wrote of it:
"For it died that autumn morning
When she, its soul, was borne
To lie all dark on the hillside
That looks over woodland and corn."
Before 1854 Lowell's literary success had been won mainly in verse. With the appearance in the magazines of A Moosehead Journal, Fireside Travels, and Leaves from My Italian Journal his success as a prose essayist began. Henceforth, and against his will, his prose was a stronger literary force than his poetry. He now gave a course of lectures on the English poets at the Lowell Institute, and during the progress of these lectures he received notice of his appointment to succeed Longfellow in the professorship of the French and Spanish languages and Belles-Lettres in Harvard College. A year was spent in Europe in preparation for his new work, and during the next twenty years he faithfully performed the duties of the professorship, pouring forth the ripening fruits of his varied studies in lectures such as it is not often the privilege of college students to hear. That pulling in the yoke of this steady occupation was sometimes galling is shown in his private letters. To W.D. Howells he wrote regretfully of the time and energy given to teaching, and of his conviction that he would have been a better poet if he "had not estranged the muse by donning a professor's gown." But a good teacher always bears in his left hand the lamp of sacrifice.
In 1857 Lowell was married to Miss Frances Dunlap, "a woman of remarkable gifts and grace of person and character," says Charles Eliot Norton. In the same year the Atlantic Monthly was launched and Lowell became its first editor. This position he held four years. Under his painstaking and wise management the magazine quickly became what it has continued to be, the finest representative of true literature among periodicals. In 1864 he joined his friend, Professor Norton, in the editorship of the North American Review, to which he gave much of the distinction for which this periodical was once so worthily famous. In this first appeared his masterly essays on the great poets, Chaucer, Dante, Shakespeare, Spenser, Milton, Dryden, and the others, which were gathered into the three volumes, Among My Books, first and second series, and My Study Windows. Variety was given to this critical writing by such charming essays as A Good Word for Winter and the deliciously caustic paper On a Certain Condescension in Foreigners.
One of the strongest elements of Lowell's character was patriotism. His love of country and his native soil was not merely a principle, it was a passion. No American author has done so much to enlarge and exalt the ideals of democracy. An intense interest in the welfare of the nation broadened the scope of his literary work and led him at times into active public life. During the Civil War he published a second series of Biglow Papers, in which, says Mr. Greenslet, "we feel the vital stirring of the mind of Lowell as it was moved by the great war; and if they never had quite the popular reverberation of the first series, they made deeper impression, and are a more priceless possession of our literature." When peace was declared in April, 1865, he wrote to Professor Norton: "The news, my dear Charles, is from Heaven. I felt a strange and tender exaltation. I wanted to laugh and I wanted to cry, and ended by holding my peace and feeling devoutly
