Alfred Lord Tennyson Announces the Birth of His First Child: An unpublished letter saying that his wife remains in recovery after the birth

It was in 1850 that Tennyson reached the pinnacle of his career, publishing his masterpiece, ""In Memoriam A.H.H."", dedicated to his close friend Arthur Henry Hallam. Later the same year, he was appointed Poet Laureate by Queen Victoria, succeeding William Wordsworth. In the same year, Tennyson married Emily Sellwood, whom he had known since childhood. In 1852, they had their first child, a son. Emily was sleepless and unwell for close to 2 weeks after the birth.,

That son, Hallam Tennyson, 2nd Baron Tennyson, would serve as the second Governor-general of Australia, in office from 1903 to 1904. He was previously Governor of South Australia from 1899 to 1902.

Mesmer's theory attracted a wide following between about 1780 and 1850, and continued to have some influence until the end of the 19th century. Like many Victorians, Tennyson had a strong interest in mesmerism.

The recipient of this letter, James Marshall, was a long time family friend who attended Hallam's baptism. The letter has been in a private collection for generations.
