Tan Keng YamEdit

I want to get this right, but I’m not sure which Tan Keng Yam you have in mind. There are multiple individuals with that name, and I don’t want to misrepresent a real person. Could you clarify:

• Is Tan Keng Yam a real public figure? If so, what is their field (politics, academia, business, etc.), nationality, and at least a couple of notable positions or achievements?
• If you’d like, I can instead draft a hypothetical encyclopedia entry for a fictional figure named Tan Keng Yam, clearly labeled as fictional. Is that acceptable?
• Roughly how long should the article be (e.g., 1,000–1,500 words, longer, shorter)?
• Any particular controversies or debates you want foregrounded from the perspective you described?
