Which electrical engineer did Lovelace visit in 1844 to learn experiments?

Ada Lovelace visited the electrical experimenter Andrew Crosse in 1844 to learn how to carry out electrical experiments.

Lovelace’s interests extended well beyond Babbage’s calculating machines. During the 1840s, she pursued natural philosophy and sought practical instruction in scientific investigation. Andrew Crosse, who lived at Fyne Court in Somerset, was known for experiments involving electricity, voltaic batteries, and crystallisation. A letter from Lovelace indicates that she was preparing to visit him at his home in November 1844.

Crosse was an unusual figure in Victorian science. He conducted electrical experiments on minerals and became controversial after reporting that tiny organisms appeared during one long-running experiment. The episode attracted sensational claims that he had created life, although Crosse himself did not present it as a successful act of creation. His electrical work nevertheless made him a useful contact for Lovelace’s practical scientific education.

The distractors were also associated with Lovelace’s intellectual circle, which makes this question easy to confuse. David Brewster was a prominent physicist, Charles Wheatstone worked on electricity and telegraphy, and George Boole was a mathematician. But the 1844 visit connected with learning electrical experiments was to Andrew Crosse.
