King Chulalongkorn the Great of Siam and the Crown Prince
Like his father, King Chulalongkorn was fascinated by western science and inventions. He traveled widely, adopting and adapting some European ways while maintaining Siam's culture and sovereignty.
The boy shown here, Crown Prince Vajirunhis, died of typhoid fever in 1895 at the age of 16. His younger half-brother, Vajravudh, went on to become King Rama VI.
