Hiram Hackenburg Killed at Clyde

Hiram Hackenburg, a well known farmer living five miles northwest of Bellevue, met with almost instant death at Clyde Saturday afternoon at 5:10 o'clock.
Mr. Hackenburg came to Bellevue that afternoon on the Lake Shore Electric, boarding the car at Carvers Corners, west of town. He spent some time visiting on the street with his sons. About four o'clock Mr. Hackenburg remarked that he believed he would go over to Clyde and see his daughter, Mrs. E. S. Munger and boarded the four o'clock car.
His daughter lives on Nelson Street in Clyde, near the electric line three streets below the waiting room and depot.
Just how the accident occurred is not clear, as it is not known that there was an eye witness to the deed. It seems that Mr. Hackenburg, who is quite deaf, was walking on the track coming toward the waiting room. He evidently did not see nor hear east bound freight car No. 56, Moterman Angus and Conductor Will Parks in charge, which came bowling along at a high rate of speed. The car struck him with great force, breaking both ankles, fracturing the left leg below the knee, and a hole was crushed in his head. The car was stopped and the victim carried to the home of his daughter, Mrs. Munger where he breathed his last as soon as they reached the home. Undertaker Supner was called and prepared the remains for burial and Sunday afternoon they were conveyed to his late home northwest of town.
Hiram Hackenburg was born and raised near Mifflinburg, Pa., and came to this vicinity thirty years ago, locating upon a farm in York Township. He was a veteran of the Civil was and his age was 68 years and 5 months. He is survived by a widow, five sons and two daughters.
The children are Samuel, who lives on a farm a short distance north of the old homestead, William, who recently purchased the Ritter farm, Jerry and Elmer of Bellevue and Frank, who is at home. The daughters are Mrs. John Boyer, of this place and Mrs. Munger, of Clyde. He also leaves one brother, Samuel H., who lives north of town.
The funeral took place from the Reformed church Wednesday afternoon at two o'clock and were largely attended. Gambee Post, G.A.R. of which deceased was member, was present in a body. The services were conducted by Rev. D. W. Loucks and the interment took place in Bellevue cemetery.
