In 1939, he presented the first PhD thesis in economics defended in Brazil, called "O Coeficiente Instantâneo de Mortalidade", which later earned him an honorary degree from the University of Havana.

He, in addition, directed the Statistics Division of the Municipality of São Paulo in the 1950s; wrote, as an amateur, articles on astronomy published in several national and foreign journals; and participated in several academies and associations, including The Econometric Tensor Society of Japan, of which he was a representative for many years.

He is the author, among others, of "Lições de Estatística", the most extensive work on the subject ever written in Portuguese and an important basic reference in the statistics teaching in Brazil.

She then opted to create a cultural center: a place for studies, research, conferences, and educational activities, to be based in the couple's old residence at Tomé de Sousa Street, in Alto da Lapa, one of the first modernist buildings in São Paulo, designed by Gregori Warchavchik in 1929.

After the approval of Municipal Law nº 8,759, in 1978, the property was included in a list of preserved assets due to its historical and aesthetic characteristics, and its destination for non-residential purposes was also authorized.

[9] The years immediately after the foundation of the cultural center were dedicated to the identification, cataloging and organization of the bibliographic, iconographic and documentary collection; and to adapting the space to receive visitors.

The reopening took place on June 28, 2000, with an exhibition of 81 old works of the bibliographic collection, produced from the 18th century on and including six rare copies, besides publications, manuscripts and newspaper articles authored by Aúthos.

The project faced resistance from Carmela Pagano and the AACCESAP, under the argument that the deed had clauses that would make the donation impossible, and that the characteristics of the bibliographic heritage kept in the space would not be compatible with the municipal public library network.

The institute expanded the permanent cultural agenda, including singing workshops and an interactive course on the history of Música Popular Brasileira (MPB).

In 2012, in celebration of its 30th anniversary, the CCESAP hosted performances by the Orquestra Paulistana de Viola Caipira, a theatrical show inspired by the biography and literary work of Patrícia Galvão, as well as lectures and soirees.

[17][18] The house at Tomé de Sousa Street where the CCESAP is located was built in 1929 and designed by Gregori Warchavchik, a Russian-born architect who was part of the first Brazilian modernist generation.

The contractor was the ophthalmologist doctor Cândido da Silva, who had purchased the land of approximately 900 m2 from Companhia City, which in turn had bought it from the French immigrant Édouard Fontaine de Laveleye in 1912.

At first the couple did not consider researching the origin or the historical and architectural value of the house, but decided to buy it because the property was on the first floor, had a large garden, and was located in a quiet neighborhood, with a flat topography and many trees.

The documentary collection consists of a large number of manuscripts and correspondence exchanged with various scholars such as Nilo Berchesi, Uruguay's Finance minister, and Professors Joseph Fayet and Octavio Morató Rodríguez, as well as a photographic archive, albums, booklets, etc.

[24][25][26] The residence preserves the original furniture used by the Pagano, such as the mahogany turned leg table, brought from Montevideo when Aúthos' family moved to Brazil; the accompanying Austrian chair; as well as the Underwood typewriter, used in the production of much of his work.
