[6] He was also appointed Secretary of Agriculture and Commerce by Governor-General Frank Murphy on July 26, 1934, re-appointed by President Manuel L. Quezon on November 15, 1935, and served as such until 1938.

However, he would begin serving his first Senate term in 1945 due to Imperial Japan's invasion of the Philippines during World War II.

He nursed the party during its darkest hours and steered it successfully through the political reefs and typhoons that rocked the local scene, thus earning him the nickname "Mr. Nacionalista".

[6] Rodriguez had seven children by his first wife, Doña Juana Santiago (1881-1954): Eulogio Jr., Jose, Ruperto, Leonor, Isidro, Constancio and Adelaida.

The grandchildren are noteworthy for refusing to name projects after themselves, a trait inculcated by Eulogio Rodriguez into his descendants.

[3] Rodriguez died in his sleep on December 9, 1964, at his home in Pasay City due to heart attack at the age of 81.

[10] Macapagal declared on December 9 until his burial a period of national mourning, where all flags would be flown at half-staff.

España Boulevard Extension in Quezon City and an avenue between barangays Rosario and Dela Paz in Pasig were renamed in his honor, as well as the municipality of Montalban.
