Violet Coulson was the wife of Tunku Abdul Rahman, the first Prime Minister of Malaysia.
Tunku had met Coulson in 1927, during his second year as a law student in London. She was an attractive lady who managed a restaurant where many Malayan students had their meals. When Tunku got tired of his law studies, he and Coulson would sometimes go dancing together. In 1933, while the Tunku was still married to Meriam, he brought Violet to visit Medan, Indonesia.
When news of Meriam's death reached Coulson she handed over the management of her restaurant in London and sailed for Singapore without the Tunku's knowledge. Upon arriving in Singapore, she wrote to the Tunku informing him of her arrival. Tunku immediately took the train to Singapore and met Coulson at her hotel. Together they talked about old times and their long friendship.
