Jonas S. Heartt died at his residence in Troy Sunday evening last [sic, he actually died on Friday 3 January, as confirmed by his obituary in other newspapers, including the one cited below], after an attack of pneumonia lasting two weeks. Mr. Heartt was born in 1830. In 1861 he married Marcia, younger daughter of Judge Hand of this village. A few years after her death he married Miss Hall, granddaughter of Ex-Gov. Hiland Hall of Vermont.

Mr. Heartt was one of Troy’s business men. He was a gentleman of strictest integrity, honest and upright in all his personal and business transactions.

By his request his remains were incinerated at the Earl crematory on the afternoon of the 6th inst. [He was actually the second person cremated at the newly established Earl Crematory, as stated in several separate articles.]

We copy the following from the Troy Times of Saturday last:

Jonas S. Heartt, who had been confined to his residence, No. 169 Second street, with pneumonia for two weeks, died at 11:45 o’clock last night.

The treacherous nature of pneumonia, the disease with which Jonas S. Heartt struggled for weeks, was particularly manifested in his case. At times he was considered to be mending rapidly and his recovery was confidently expected. Then hope would be suddenly destroyed by alarming symptoms which threatened to immediately terminate the life of the sufferer. He made a hard fight for life, but the disease proved fatal as above stated.

Jonas S. Heartt was the youngest son of Jonas Coe Heartt, who was prominently identified with the earlier history of the city. He was born in Troy December 31, 1830, and prepared for college in the schools of this city. After his graduation from Union college he became a clerk in the hardware store of Heartt & Co., and at one time had an interest in the business. He left the hardware trade many years ago and engaged in the manufacture of fire-brick with James Ostrander in the lower part of the city.

Seventeen years ago he became interested in the manufacture of car-wheels. At the time of his death Mr. Heartt was at the head of the firm of Jonas S. Heartt & Co., of the Empire car-wheel works at the corner of Second and Ida streets.

Many years ago Mr. Heartt married Miss Marcia Hand, daughter of Judge Hand of Elizabethtown, N.Y. Mrs. Heartt died some years later. Mr. Heartt afterward married Miss Hall, granddaughter of ex-Gov. Hiland Hall of Bennington, Vt. She died about three years ago.

A daughter and a son, Fannie and Jonas C. Heartt, survive. A sister of the deceased, Miss Mary W. Heartt, also survives. She is a resident of New York. Another sister, Mrs. Edward Schell, died a short time ago in New York.

Mr. Heartt was a director of the Mutual national bank, having succeeded his father in that position. He was also a member of the Troy club. Mr. Heartt was one of the organizers of the B. G. society, and was among its members at the time of his death. He avoided active political life and never held public office.

Mr. Heartt’s father, Hon. Jonas Coe Heartt, at the time of his death in 1874 was the oldest native-born inhabitant of Troy. He was once speaker of the assembly and held several political offices in that city. His connection with city affairs began in 1822, when he was elected alderman from the second ward. In 1833, ’35 and ’36 he represented the ward in the board of supervisors. In 1838 he was elected mayor and was re-elected until 1848, when he declined a renomination. Aside from these offices and his active interest in the hardware trade, Jonas C. Heartt was busily engaged in the affairs of other institutions. For many years he was a trustee of the Rensselaer polytechnic institute, and was long the honored president of the Troy female seminary. The wife of Jonas C. Heartt was Catherine Lamberson, who was born at Jamaica, L. I. They had nine children, Jonas S. being the youngest.

Mr. Heartt was first attached by influenza, the prevailing disease. While he was recovering from that malady he caught cold, which brought on pneumonia. His strong constitution enabled him to make a persistent but unavailing struggle.

Mr. Heartt was recognized as one of Troy’s solid business men. He was a gentleman of the strictest integrity, honest and upright in all his personal and business transactions. He was at the head of a large manufacturing establishment, and the success of that enterprise was due to his excellent business qualifications. Mr. Heartt was devoted to his family, and his circle of friends was widely extended. A good citizen, and a kind and loving husband and father, has been taken away.

Mr. Heartt was a member of St. John’s church, and for several years was a vestryman.
