Juan B. Alegre was born on February 2, 1882, in Casiguran in the province of Sorsogon in the Bicol Peninsula. In 1926, he later moved residence to what is now known as Barangay San Juan in Irosin.
Alegre was an abaca plantation owner[9] and reportedly one of the wealthiest citizens[10] of the Philippines of his time. He was the president of the Chamber of Commerce of the Philippine Islands from 1920 to 1921, and one of the financiers of the Philippines Herald[11][12][13] newspaper.[1] Juan B. Alegre was married to Amanda Sargent[14][15][16] and survived by four of his children.
On behalf of the Demócratas, he succeeded afterwards in being re-elected again to the Senate. But before Alegre could take his place in the 9th Philippine Legislature, however, he died in his home in Manila after being sworn to office[20] at the age of 49,[21] on June 14, 1931[22] from complications of gastric ulcer.[23][24] His vacancy was filled by Jose O. Vera[25][26] by a special election later that year.[27] A street fronting the Sorsogon Provincial Capitol and Park in Sorsogon City is named in his honor.[28][29]
