[1] He was baptized on April 14, 1827, by Pastor Carl Leopold Voges [pt], having as godfather his homonymous uncle João Niederauer, at the time installed with a commercial house next to Baluarte Ipiranga, in Vila de Torres.

João Niederauer at the age of 23, volunteered and was appointed Lieutenant of the 1st Cavalry Corps of the National Guard of the District of Santa Maria.

His stay at home was short-lived and as early as March 1854, just 3 months after the birth of his firstborn, Delfina, Captain Niederauer was called to join his Squadron of the Santa Mariense National Guard which was part of the Imperial Auxiliary Division.

Probably for this reason, he ceased to participate in the City Council that installed the new Vila de Santa Maria da Boca do Monte on May 17, 1858.

In the following elections on September 7, 1864, he was the most voted councilor but stopped taking office due to the outbreak of the Uruguayan War and Niederauer was called for active service again.

[1] His remains weren't identified for a long time until they were recovered by his great-great-grandson, Juan Farinolli Niederauer and they were repatriated at his home state of Rio Grande do Sul.

[1] The Brazilian Army honored him on the centenary of his death in 1968, naming the Vila Militar on Avenida Borges de Medeiros after him and in 1992, enshrining him as the Patron of the 6th Armored Infantry Brigade whose headquarters, as well as 11 of its 14 military organizations, are in Santa Maria.

The two columns of the loft, which decorate the graduation patio of the Headquarters of the 6th Armored Infantry Brigade, symbolize the bases of the military profession which Niederauer was described as having hierarchy and discipline.
