Henry Stephens was born in
Holborn, London, the second son of Joseph Stephens (1771–1820) and his wife Catherine (1763–1843), née Farey, but along with his elder brother John was soon moved to more rural
Hertfordshire. The family lived briefly in
Hatfield where sisters Frances (1798–1860) and Catherine (1800–1855) were born. Around 1801 they moved to
Redbourn near
St Albans where a fifth child, Josiah (1804–1865) was born. Joseph Stephens became the innkeeper at
The Bull, the principal inn and busy staging-post in Redbourn High Street on a main stagecoach route between London and the north. In 1811 Stephens was apprenticed to a local doctor in
Markyate three miles north of Redbourn and in 1815 enrolled as a pupil in the united teaching school of
Guy's and
St Thomas' Hospital in London. He shared lodgings at 28 St Thomas Street,
Southwark, with George Wilson Mackereth, whose daughter Stephens's son,
Henry Charles, later married, and with
John Keats, who was to become famous as a poet, and who died in Rome in 1821. It is on record that in 1816 Stephens helped Keats compose the line from
Endymion book 1, "A thing of beauty is a joy forever ...". On 14 March 2002, as part of the 'Re-weaving Rainbows' event of
National Science Week 2002,
Poet Laureate Sir
Andrew Motion unveiled a blue plaque on the front wall of 28 St Thomas Street to commemorate the sharing of lodgings there by Keats and Stephens while they were medical students at Guy's and St Thomas' Hospital in 1815–16. ==Redbourn, 1817–1828==
