James Ray Tinkcom was born January 29, 1821, at Mayville, New York, the son of Hezekiah and Anna (Sprague) Tinkcom. His father was a prominent figure in Chautauqua County, keeping a hotel in Mayville for many years and serving for a time as sheriff and jailer of the county. Young James was educated at the academy in his native town.

In 1841 he began the study of medicine, pursuing it for two years, though he never entered active medical practice. For a short time he manufactured proprietary medicines, then assisted in managing his father’s hotel. During the five years immediately preceding his move west, he was engaged in the grocery business.

On May 2, 1851, he married Miss Laura A. Davis at Sugar Grove, Pennsylvania. They would have one child, Mary L., who later became the wife of O. G. Lundberg of Mankato.

Tinkcom came to Minnesota in 1856, arriving in Mankato on November 10 of that year. After purchasing property and deciding to make the town his permanent home, he returned briefly to New York to settle his affairs and came back to Mankato early in the spring of 1857.

Soon after his return, he formed a partnership with A. F. Hawley, whom he had known in New York. Together they built on the lot later occupied by the L. Patterson wholesale house and opened a general merchandise store under the name A. F. Hawley & Co. The partnership dissolved in the spring of 1861. Tinkcom then entered the drug business, eventually operating two drug stores—one managed personally and the other by Jason F. Wickersham.

His business ventures expanded into real estate. In 1873 he purchased land on the south side of Mankato and laid out what became known as Tinkcom’s Addition, a development that permanently shaped the city’s growth. From 1863 onward, he devoted himself largely to managing his real estate interests.

Beyond commerce, Tinkcom played an active role in civic and religious life. He was one of the organizers of the Mankato Episcopal Church and served one term as City Treasurer. He aided materially in nearly every enterprise connected with the city’s advancement and was widely regarded as a public-spirited pioneer.

After more than fifty years in Mankato, James R. Tinkcom died at his home on James Avenue on the morning of March 7, 1908, at 1:30 o’clock, following several weeks of illness. General senility contributed to his decline, but the immediate cause of death was uremia (kidney failure). He was eighty-seven years old.

Newspaper accounts described him as one of the oldest and best-known residents of the city—a man of generous impulses and genial nature who possessed a wide circle of friends. In his later years he lived quietly at his home in the addition that bore his name.

Funeral services were held from his residence, and interment took place at Glenwood Cemetery. His passing marked the loss of one of Mankato’s earliest pioneers and most respected citizens.

In later years, Tinkcom gained an additional place in local cultural history: he served as the inspiration for the character Mr. Meecham in Maud Hart Lovelace’s Betsy-Tacy and Deep Valley books, ensuring that his legacy would endure not only in the city’s geography but also in its literature.
