His father was Huad and his mother was Kao.
His original name was Kon Hutasingh.
He was a very intelligent student.
After graduating from the law school in Bangkok in 1903 with the degree of Barrister-at-law.
he won a government scholarship to continue his studies at the middle Temple in England in 1905.

he returned to thailand and served in the Ministry of Justice during the last part of the reign of King Chulalongkorn.
Before the Revolution of 1932 he was a judge of the Court of Appeal and a member of the privy Council in the reign of King Prajadhipok (Rama VII)
After the revolution,Dr Pridi Banomyong suggested the People's party should select Phraya Manopakornnitithada to be President of the people's Committee which was the most important position in the new government.
Dr pridi thought that Phraya Manopakornnitithada was a commoner with a good educational background from such a democratic country as England,so he should be in favour of democratic system and, above all, he enjoyed a certain relationship with King Prajadhipok as his wife was also one of the Queen's ladies-in-waiting.
So, he was seen as an ideal compromise between the revolutionary party and the King.
He took the post of President on 28 June 1932.
Later, when the Permanent Constitution of December 10, 1932 came into force,the members of the Preple's Committee resigned to allow for the formation of a true cabinet.
Phraya Manopakornnitithada was then appointed Prime Minister to lead the new form of government.
On April 1,1933 Prime Minister Phraya Manopakornnitithada ordered the prorogation of the National Assbly and suspension of certain articles of the permanent constitution reasonion that the cabinet could not agree on a national econamic policy submitted by dr pridi banomyong as it inclined towards communism.
as a result dr pridi was relieved of all posts and advised by the government to leave the country and he left thailand for france on 12 april 1933.
indeed phraya manopakornnitithada's action caused much dissatisfaction to most leading members of the people's party and the goveenment.
consequently on 20 june 1933 the government of phraya manopakornnitithada was forced to resign by a coup led by phraya phahol pholphayuhasena.
he went into self-exile at penang where he lived out his days.
he died on 1 october 1948 at the age of 64.
