The question "Who is he?" is very broad and requires context to identify which specific person "he" refers to. Without additional details, it is not possible to provide a precise identity. If you are asking about the phrase "Who’s Who," it refers to a well-known reference work listing notable people who influence society, especially in the UK and internationally. The book "Who's Who" has been published annually since 1849 and includes biographies of prominent figures in government, academia, business, and the arts, serving as a directory of influential individuals.
If the question relates to identifying a person indirectly referred to as "he," please provide more context or details such as the person's field, location, or accomplishments. Otherwise, "Who is he?" remains an open, unspecific query.
