Marcel Alphonse Joseph Maquet was born in Huy, Liège Province, Belgium on 1 November 1891.

[1] Maquet began his service in Boma on 19 June 1919, and was assigned to the Yokolo Territory in Équateur Province.

He helped organize the chiefdoms and the workforce, improved the roads and developed cotton cultivation in Équateur.

[2] Macquet took an interest in locally made ivory carvings and tools, some dating to the pre-colonial period, and later wrote about them in the journal of the Musée de la vie indigène in Leopoldville.

[7] In a letter of 5 December 1939 to Governor General Pierre Ryckmans Maquet opposed clemency for former leaders of the Kimbanguist movement had converted to the Salvation Army, since they distorted the teachings of the Salvation Army in their speeches to large crowds, and continued to support the movement.

[8] On 20 December 1939 vice-governor Paul Ermens wrote to Maquet about the relegation of Simon-Pierre Mpadi before the opening of the Agricultural Colony of Boende.

[11] He was responsible for a province where a large number of colonial troops were stationed with a view to possible intervention in Abyssinia.

Some of the Europeans were angry at the delay in taking action, but Maquet and General Auguste Gilliaert managed to calm the situation.
