Mr. Heartt was born in Troy, in 1793, and in early life went into the hardware business with his brother, under the firm name of Jonas C. Heartt & Bro. In 1847 he retired with a competency, and the business was continued by his son, Charles F. Heartt, who died on the 4th of March last. Mr. Heartt previous to the year 1836 was several times elected to the Common Council of his native city, and in that year was elected Mayor, which office he held until 1842. In 1854 he was elected to the Assembly, and was chosen Speaker. He was always closely identified with the interests of the City of Troy, and was very energetic in his exertions to forward its steam-boat and railroad enterprises. He was one of the Trustees of the Rensselaer Polytechnic Institute at the time of his death, and had occupied the same position for fifty years. He was characterized by amiability and kindliness, and was highly respected by his fellow citizens. Mr. Heartt leaves three children, a son and two daughters.

Hon. Jonas Coe Heartt, son of Phillip Heartt, was born in Troy, N.Y., August 12th, 1793. He was a member of the class of 1811 in Union College. His life was closely interwoven with the interest of Troy; he grew up with it, and helped to make it what it is. He was not a seeker of public positions, but was sought for as one peculiarly fitted to represent the city both at home and in the Legislature, where he was made speaker by a flattering vote. His connection with city affairs began in 1822, when he was elected assistant alderman for the second ward. He was also a supervisor of this ward for 1833, 1835, and 1836, and in 1838 he was elected mayor, and re-elected each following year until 1843, when he declined the nomination.

It was through the united efforts of Mr. Heartt and Jonathan Edwards that Troy was made the terminus instead of a branch of the Hudson River Railroad. Mr. Heart was instrumental in having a direct line of steamboats from Troy to New York, and for twelve years was a director in the River Steamboat Association. He was a director of the Troy & Boston Railroad from the time of its construction until his decease. He was the first president of the board of trustees of the fire department, and for many years was a member of the board of fire commissioners. After the death of Mr. Marshall, Mr. Heartt was made president of the board of governors of the Marshall Infirmary, and through his efforts a debt of eighteen thousand dollars against the institution was paid off in one year. Upon the formation of the Mutual Bank he was a director, which office he held, in connection with presidency of the Mutual Savings Bank, until his death. He was interested in the Rensselaer Polytechnic Institute, of which for years he was a trustee, and also of the Troy Female Seminary, of which he long was the honored president. With all these interests so beneficial to the city, he was for more than forty years was actively engaged in the hardware business, which was founded by his father in 1798. Mr. Heartt was chosen a member of the vestry of St. Paul’s Church on Easter Monday, 1831, and constantly until 1861, when he was chosen church warden. He was a member of that church for nearly fifty years, and aided it with wise counsel, active exertion and liberal contributions. He was a good friend, remarkably strong in his attachments and strictly honorable in all his business relations.

He was the first child baptized by the first pastor of the Troy First Presbyterian church, and for this reason he was given the name of the pastor, Jonas Coe. His life was closely interwoven with the interests of Troy; he grew up with it, and helped to make it what it is. To his intelligent counsel can be attributed many of the successful enterprises, both moral and educational, that are now the pride of the city.

He was also supervisor of this ward for 1833, ’35, and ’36, and in 1838 he was elected mayor and re-elected each following year until 1843, when he declined the nomination. During these years many advantages were gained to Troy which were due to his prudence and quick-sightedness.

It was through the united efforts of Mr. Heartt and Jonathan Edwards that Troy was made the terminus instead of a branch of the Hudson River Railroad. Mr. Heartt was instrumental in having a direct line of steamboats from Troy to New York, and for twelve years was a director in the River Steamboat Association. He was a director of the Troy and Boston Railroad from the time of its construction until his decease.

David Buel, Jr.; and he was a member of that church for nearly fifty years, and aided it with wise counsel, active exertion, and liberal contributions. He was a good friend, remarkably strong in his attachments, and strictly honorable in his business relations. He was genial and entertaining, and rarely can a man be found so free from deceit.
