I want to know the answer to the following question:
Who did Bell meet in 1874?
All the background I'm provided with is that "In March 1875, Bell and Pollok visited the famous scientist Joseph Henry, who was then director of the Smithsonian Institution, and asked Henry's advice on the electrical multi-reed apparatus that Bell hoped would transmit the human voice by telegraph.". Is that enough to answer the question?
Answer: no
