Humphry Davy married Jane Apreece, a wealthy widow and the daughter of Charles Kerr of Kelso. She was known for her intelligence, social connections, and independent spirit. The marriage brought him financial security and access to higher social circles. However, the marriage was not always harmonious, marked by tensions and differing personalities.

Davy and his wife embarked on an extended continental tour. Despite wartime conditions (Napoleonic Wars), Davy was granted special permission to travel to France, where he met with prominent scientists like Gay-Lussac and Ampère. Michael Faraday accompanied him as his assistant during this tour.

Davy was elected Fellow of the Royal Society. This marked his acceptance into the scientific establishment.

Davy cultivated relationships with influential members of society, including politicians, aristocrats, and fellow scientists. His social skills and charisma helped him to advance his career and secure funding for his research. His connections also provided him with access to powerful patrons who supported his work.

As Davy's health declined in his later years, he became increasingly isolated from social activities. His frequent illnesses and travels for medical treatment limited his ability to maintain his previous level of social engagement. His relationship with Jane also suffered and she was in Rome at the time of his death.
