Ignatius Joseph Kasimo Hendrowahyono

Hendrowahyono became a member of the Central Indonesian National Committee in 1945. Within the same time period, Hendrowahyono also started the process of consolidating several Catholic political parties in Indonesia into one entity: the Indonesian Catholic Party (Indonesian: Partai Katolik Republik Indonesia). He also started focusing on agricultural and plantation issues plaguing the nation. This interest culminated in his appointment as the Secretary of Agriculture and Secretary of Commerce. He also maintained strategic parliamentary positions as Indonesia underwent several governmental changes, including during the United States of Indonesia period.

While studying at Middelbare Landbouw School, Hendrowahyono joined the youth organization Jong Java, which was associated with the Youth Pledge declaration. In 1923, he started a political party called the Catholic Javanese Political Party (Indonesian: Pakempalan Politik Katolik Djawi) which by 1933 became known as the Indonesian Catholic Political Party (Indonesian: Persatoean Politik Katolik Indonesia). Hendrowahyono also became a member of Volksraad from 1931 to 1942 and was involved in the committee behind the Soetardjo Petition.

Owing to his father's prestigious position in that era, Hendrowahyono was able to attend school in the Dutch East Indies. He first attended Tweede Inlandsche School in Kampung Gading. Later on, he entered a teaching college in Muntilan, where he was introduced to Catholicism by the school's founder, Romo (Father) van Lith. He was baptized in 1913 and received his Christian name Ignatius Joseph. He moved to Britenzorg (now Bogor) in 1918 to continue his studies at Middelbare Landbouw School.

Ignatius Joseph Kasimo Hendrowahyono (10 April 1900 – 1 August 1986) was an Indonesian politician and national hero. He helped form the Partai Katolik and was himself a Catholic.
