In 1828 Charles and Alfred Tennyson matriculated at Trinity College, Cambridge, where their elder brother Frederick had already been for some time. Alfred was a somewhat shy lad, and did not at once take kindly to the life of his college. He soon, however, found himself one of a famous society known as "The Apostles," to which belonged some of the best men in the University. Not one member of the "Apostles" at this time, but afterwards made a name for himself, and made his influence felt in the world of politics or letters. The society met at regular intervals, but Alfred did not take much part in the debates, preferring to sit silent and listen to what was said. All his friends had unbounded admiration for his poetry and unlimited faith in his poetic powers. This faith was strengthened by the award of the University Prize for English Verse to Alfred in June, 1829. He did not wish to compete, but on being pressed, polished up an old poem that he had written some years before, and presented it for competition, the subject being Timbuctoo. The poem was in blank verse and really showed considerable power; in fact it was a remarkable poem for one so young.

Perhaps the most powerful influence on the life of Tennyson was the friendship he formed while at Cambridge with Arthur Henry Hallam, the son of the historian, Henry Hallam. The two became inseparable friends, a friendship strengthened by the engagement of Hallam to the poet's sister. The two friends agreed to publish a volume of poems as a joint-production, but Henry Hallam, the elder, did not encourage the project, and it was dropped. The result was that in 1830, Poems, Chiefly Lyrical, was published with the name of Alfred Tennyson alone on the title page. The volume was reviewed enthusiastically by Hallam, but was more or less slated by Christopher North in the columns of Blackwoods' Magazine. Tennyson was very angry about the latter review and replied to the reviewer in some caustic, but entirely unnecessary, verses.

In the same year Hallam and Tennyson made an expedition into Spain to carry aid to the rebel leader against the king of Spain. The expedition was not by any means a success. In 1831 Tennyson left Cambridge, without taking his degree, and shortly after his return home his father died. The family, however, did not remove from Somersby, but remained there until 1837. Late in 1832 appeared another volume entitled Poems by Alfred Tennyson. This drew upon the unfortunate author a bitterly sarcastic article in the Quarterly, written probably by its brilliant editor, John Gibson Lockhart. The result of this article was that Tennyson was silent for almost ten years, a period spent in ridding himself of the weaknesses so brutally pointed out by the reviewer.

In 1833, Arthur Henry Hallam died, and for a time the light of life seemed to have gone out for Alfred Tennyson. The effect of the death of Hallam upon the poet was extraordinary. It seemed to have changed the whole current of his life; indeed he is said, under the strain of the awful suddeness and unexpectedness of the event, to have contemplated suicide. But saner thoughts intervened, and he again took up the burden of life, with the determination to do what he could in helping others. From this time of storm and stress came In Memoriam.

From 1832 to 1842 Tennyson spent a roving life. Now at home, now in London, now with his friends in various parts of England. He was spending his time in finishing his poems, so that when he again came before the world with a volume, he would be a master. The circle of his friends was widening, and now included the greater number of the master-minds of England. He was poor, so poor in fact that he was reduced to the necessity of borrowing the books he wished to read from his friends. But during all this time he never wavered in his allegiance to poetry; he had determined to be a poet, and to devote his life to poetry. At last in 1842 he published his Poems in two volumes, and the world was conquered. From this time onwards he was recognized as the leading poet of his century.

In 1845, Tennyson, poor still, was granted a pension of 200 pounds, chiefly through the influence of his friend Richard Monckton Milnes, and Thomas Carlyle. There was a great deal of criticism regarding this pension from sources that should have been favorable, but the general verdict approved the grant. In 1847 appeared The Princess, a poem, which, at that time, did not materially add to his fame; but the poet was now hailed as one of the great ones of his time, and much was expected of him.

In 1850 three most important events in the life of Tennyson happened. He published In Memoriam, in memory of his friend, Arthur Henry Hallam; he was appointed Poet Laureate, in succession to Wordsworth; and he married Emily Selwood, a lady to whom he had been engaged for seventeen years, but whom his poverty had prevented him from leading to the altar. From this time onwards the life of the poet flowed smoothly. He was happily married, his fame was established, his books brought him sufficient income on which to live comfortable and well. From this point there is little to relate in his career, except the publication of his various volumes.

After his marriage Tennyson lived for some time at Twickenham, where in 1852 Hallam Tennyson was born. In 1851 he and his wife visited Italy, a visit commemorated in The Daisy. In 1853 they removed to Farringford at Freshwater in the Isle of Wight, a residence subsequently purchased with the proceeds of Maud, published in 1855. The poem had a somewhat mixed reception, being received in some quarters with unstinted abuse and in others with the warmest praise. In the year that Maud was published Tennyson received the honorary degree of D.C.L., from Oxford. In 1859 was published the first four of the Idylls of the King, followed in 1864 by Enoch Arden and Other Poems. In 1865 his mother died. In 1869 he occupied Aldworth, an almost inaccessible residence in Surrey, near London, in order to escape the annoyance of summer visitors to the Isle of Wight, who insisted on invading his privacy, which, perhaps, more than any other he especially valued.

From 1870 to 1880 Tennyson was engaged principally on his dramas—Queen Mary, Harold, and Becket,—but, with the exception of the last, these did not prove particularly successful on the stage. In 1880 Ballads and Poems was published, an astonishing volume from one so advanced in years. In 1882 the Promise of May was produced in public, but was soon withdrawn. In 1884 Tennyson was raised to the peerage as Baron Tennyson of Aldworth and Farringford, after having on two previous occasions refused a baronetcy. In 1885 Tiresias and Other Poems was published. In this volume was published Balin and Balan, thus completing the Idylls of the King, which now assumed their permanent order and form. Demeter and Other Poems followed in 1889, including Crossing the Bar. In 1892, on October 6th, the poet died at Aldworth, "with the moonlight upon his bed and an open Shakespeare by his side." A few days later he was buried in Westminster Abbey, by the side of Robert Browning, his friend and contemporary, who had preceded him by only a few years.

Carlyle has left us a graphic description of Tennyson as he was in middle life: "One of the finest—looking men in the world. A great shock of rough, dusky dark hair; bright, laughing hazel eyes; massive aquiline face—most massive yet most delicate; of sallow brown complexion, almost Indian-looking; clothes cynically loose, free-and-easy; smokes infinite tobacco. His voice is musically metallic—fit for loud laughter and piercing wail, and all that may lie between; speech and speculation free and plenteous; I do not meet in these late decades such company over a pipe! We shall see what he will grow to." To this may be added a paragraph from Caroline Fox: "Tennyson is a grand specimen of a man, with a magnificent head set on his shoulders like the capital of a mighty pillar. His hair is long and wavy and covers a massive head. He wears a beard and mustache, which one begrudges as hiding so much of that firm, powerful, but finely-chiselled mouth. His eyes are large and gray, and open wide when a subject interests him; they are well shaded by the noble brow, with its strong lines of thought and suffering. I can quite understand Samuel Lawrence calling it the best balance of head he had ever seen."
