He is remembered for giving rise to the science of astronomy in inter-war Lithuania, helping to raise a new generation of astronomers including Paulius Slavėnas, Antanas Juška, and Česlovas Masaitis.

Kodatis's house in Berlin quickly became a transit point for Lithuanian figures arriving or traveling further to Europe or the United States.

He also prepared a scientific study about the results of his measurements while he was in the last grade of the gymnasium, which was particularly well evaluated by the researchers of the University of Berlin.

He graduated with a doctor's degree[3] in 1910,[4][5] Kodatis was invited to study astronomy or mathematics, but following his uncle's advice joined a teachers' seminary.

After graduating from the teachers' seminary, Kodatis nonetheless began studying astronomy, working as a mathematician in an observatory in the meantime.

After finishing his studies, Kodatis did not stay at the university or the observatory, and instead moved to Lithuania Minor to teach along with his wife Viktorija Kodatienė née Gruzdytė.

[4] However, after a few weeks of service, Kodatis was sent to edit the newly established Lithuanian-language newspaper Dabartis, as he was already a known astronomer and editor in Germany.

Since German authorities prohibited the publishing of the Act of Independence of Lithuania, Kodatis made sure that the document would be delivered to pro-Lithuanian Reichstag deputies in Berlin.

After German intelligence learned of Kodatis's actions, he was arrested in Endružiai after being demobilized and consequently jailed in Tilsit for "betrayal of the fatherland".

He helped uncover the plot of the Polish Military Organisation, and participated in the Klaipėda Revolt as a negotiator with the commanders of English and French warships.

[1] Kodatis's astronomical work in mainly consisted of determining the coordinates of Lithuanian settlements and researching the Sun, Moon, and meteorites.

It was planned since 1927 to carry out triangulation works that covered 80 points in Lithuania with three main bases: Švėkšna, Skapiškis and Kaunas.

After his son Kęstutis Augustas and wife settled in the United States and found a job, Kodatis, who was living in Wangen im Allgäu from 1944,[4] got permission to join them in the country in 1951.
