ALBERT CHELLBORG DEAD

THE PROPRIETOR OF A FAMOUS BAKERY PASSES AWAY.

Albert Chellborg, the proprietor of the bakery at Twenty-third-street and Third-avenue, where the students at the very best of colleges in that vicinity have lunched from time immemorial, died very suddenly of apoplexy at his rooms over the bakery Thursday afternoon. He was seventy-eight years of age, and was making arrangements to retire from the business in favor of his eldest son on May 1. These arrangements included the erection of a handsome house at Sea Cliff, L.I., where he intended to make his residence, and he had been up there looking after the finishing work on the building during the afternoon. He came back to the city at 4:30 o'clock, jumping off the horse car as it passed his door as lightly as a schoolboy and feeling in perfect health. He complained of a pain in his chest after he went up stairs, however, and fell dead an hour later.
Mr. Chellborg was born near Stockholm, Sweden, and after graduating at the Upsala University and serving a year in the cavalry ranks of the Swedish Army, came to this country in 1835. He went down to Texas with several of his countrymen to settle and grow up with the Lone Star State. After twenty years down there, and having experiences that he loved to relate to his friends in after life, Mr. Chellborg returned to the North and settled at Geneva, in Ontario County, this State, where he managed a farm until 1866, when he came to New York and established the bakery that made his name one of the most familar in the city.
His widow and seven children, four sons and three daughters, survive him. The funeral services will be held at 3:30 o'clock to-morrow afternoon at St. Paul's Church, Twenty-second-street and Fourth Avenue.
