I believe you might be referring to Tohru Himuka (also spelled as Himuka Tooru in the Japanese naming convention), who is a Japanese chemist recognized for his contributions to the field of inorganic chemistry, particularly related to bioinorganic chemistry and coordination chemistry. However, I could not locate significant information about Tohru Himuka as a widely known public figure or author in fields like literature or popular nonfiction. It is possible that there may be a less prominent author with this name, or that the name has been misspelled or confused with someone else. If the person you're referring to is involved in a specific niche, providing additional context might allow for a more accurate description.
