Foster Blodgett, Jr. was born in Augusta on the 15th of January 1826, son of Foster Blodget, Sr. and Susan Eliza Perdue Blodget. He was in the 52nd year of his age at the time of his death.

In Augusta, GA, Foster was elected bridge keeper by the city council January, 1850, and held that office for two years. In 1853, he was elected member of council from the first ward, and held that position with the exception of 1852, until April, 1859, when he was elected Mayor. He was re-elected in 1860, and was a candidate in 1861, but was defeated by Robert H. May. He was ordinary of Richmond County from February 1855, to July, 1861.

During the War Between the States, Foster was Captain of the Blodgett Artillery from Augusta. After the war, he joined the Republican Party, and was an active member of that organization. In 1865, at the close of the war, Foster was appointed postmaster by President Johnson, but was removed in January, 1868 and General Summers placed in charge of the office as special agent of the department. Blodgett was reinstated by President Grant April 5th, 1869. He remained postmaster until July 1st, 1869, when Captain J. E Bryant was appointed. Blodgett was President of the Republican Party of the city in 1867.

In May, 1867, Blodgett was appointed Mayor of Augusta by General Pope Military Governor of Georgia, and retained that position until December, 1868, when Hon. H. F. Russell was elected mayor. In 1867 he was elected a delegate to the Constitutional Convention. February 15, 1870, the Republicans in the State Legislature voted for him for United States Senator from Georgia, and claimed that he was elected to that position. The Democrats in the legislature who declined to vote, protested against the election, which they declared was illegal and void, because the legislature in 1863 elected two senators to serve, one until March 1873, and the other until March, 1871, and that it was the province of the legislature to be elected in November, 1870, and which would sit in January, 1871, to elect their successors, and not the then legislature. Joshua Hill, then Senator in Congress from Georgia, opposed Mr. Blodgett's admission, and the Senate did not admit him. At one time, Mr. Blodgett was Treasurer, and afterwards Superintendent of the State Road. After the return of the Democrats to power, in Georgia, Mr. Blodgett moved to Newberry, South Carolina, and remained there for some months, when he took up his residence in Atlanta.

On November 12, 1877, Foster Blodgett, Jr. died of typhoid fever and on November 13, 1877, the funeral was held at the First Baptist Church in Atlanta. The pall bearers at the funeral were former Governors of Georgia: Joseph E. Brown and Benjamin Conley. Also, United States District Attorney Henry P. Farrow and Attorney at Law, Daniel P. Hill were also pall bearers. According to his obituary in the Atlanta Constitution, Foster Blodgett, Jr. was buried beside the grave of his little son, which would have been Oliver Morton Blodgett that died in 1870. Blodgett's tombstone has an incorrect death date of 1887. (This is a new tombstone.) In the Oakland Cemetery burial records, he has been mixed up with his infant grandson, Edwin Foster "Edward" Blodgett, son of Edwin Ford Blodgett. That is why his tombstone has 1887 instead of 1877. He also was buried in a brick vault in grave 12 not 14B. Grave 14B is the remains of infant grandson, Edwin Foster "Edward" Blodgett.

Foster Blodgett Jr.'s first wife was Louisa Maria Foster of Augusta, GA. They had 5 children named Susan, Edwin, Caroline, John, and Thomas. His second wife was Emma Pool of Greenville, SC. They had seven children named Jessie, Jordan, Jordan, Rufus, Oliver, Emma & Foster.
