Reinhard was born January 31, 1841, in Leimersheim, Germany to Johannes Liebel and Eva Hammer Liebel. Liebel was one of six children, all of whom were born in Leimersheim, Germany. Along with their parents, they immigrated to the United States in 1857 aboard the SV Argo from Le Havre (the second largest port in France) to New York City. The children were: Jacob Liebel (1834-1880), George Philip Liebel (1836-1893), Francis Peter Liebel (1838-1895), a Justice of the Peace and Alderman in Erie who received his commission April 25, 1871. In 1887, Francis, at one time one of the wealthiest citizens of Erie, was arrested after his store was seized by police. According to news reports at the time, Liebel and a posse attacked the store that police had taken possession of with an axe and drove the deputies from the premises, Reinhard Liebel (1841-1905), Michael Liebel (1843-1906), and Maria Frances Liebel (1845-1850).
Through his brother, Michael, and his sister-in-law, Clara Maria Uhr (who was also a sister to Reinhard's wife), he was uncle to Michael Liebel, Jr. (1870-1927), the Mayor of Erie, Pennsylvania, from 1906-1911, and a Democratic member of the United States House of Representatives from Pennsylvania, from 1915-1917.
Liebel was the President of the South Erie Iron Works during the boom years of Iron in Erie. South Erie Iron Works was established by Adam Acheson and William Henry on Peach Street in 1858 and was incorporated in 1868. It produced stoves and general iron works and was headquartered at 1917 Peach Street (built from 1871-1891) in Erie with the foundry at 26th and Maple Streets (built from 1885-1887). In 1896, Liebel was President, John G. Liebel (Reinhard’s son) was Corporate Secretary, and A. K. Acheson was Treasurer. The principal stockholders were Reinhard, John G. Liebel, Adam K. Acheson, D. S. Clark, Tobias S. Alberstadt, John Henry Kalvelage (former owner of the Eagle Brewery), D. T. Jones, Mrs. William Henry, Ph. Deifenbach, and James Leask.
In 1898, Liebel’s son, John G. Liebel along with John Depinet, purchased the Chicago and Erie Stove Works in Erie, founded by William Himrod. The purchase included all patents, designs, and patterns. Up to that point, John had been connected with Reinhard's South Erie Iron Works. Liebel and Depinet continued to operate the company under the old name, but utilized the business and methods from South Erie Iron Works.
The Liebel’s also ran the Liebel House, a hotel, which opened January 1, 1887 at 1101-1114 State Street in Erie, on the site of the old Keefer House (also known as the United States Hotel). The hotel was the largest in Erie next to the Reed House, and it was originally called the Arlington. It was renamed to the Liebel House to honor the builders after several years.
The hotel was in operation until October 1901 when a large boiler in the brass foundry of the Hayes Manufacturing Company on West 11th Street exploded and completely demolished the Hayes building and an adjoining building that directly backed up, and connected with, the Liebel House by a covered passageway across the alley. At the time of the explosion, dinner was being served, and six women who were in the kitchen of the Liebel House perished in the wreck. The drift of the explosion passed through the hotel bar with that part of the hotel completely wrecked. The hotel itself was seriously damaged with all the plate glass windows wrecked and was eventually demolished. Damage to the Hayes Manufacturing Company building and the hotel amounted to about $50,000 (equivalent to $1,439,000 in 2016).
Reinhard was a staunch Democrat and served the City of Erie in several official positions:Member of the Board of Fire Commissioners from 1887-1892
Common Council under Mayor David T. Jones in 1880
Common Council under Mayor Joseph McCarter in 1881
Select Council under Mayor Joseph McCarter in 1882
Common Council under Mayor Philip Becker in 1883
Liebel’s brother, Michael Liebel (1843-1906), also served on the Common Council from 1871-1875, of which he was President from 1873-1874 (under Mayor Charles M. Reed and Mayor Henry Rawle). In 1876, he served as President of the Select Council under Mayor John W. Hammond. From 1877-1881, Michael was on the Board of Commissioners of Erie Water Works. From 1904-1906, Michael was on the Board of Railroad Crossing Commissioners.
Liebel married Mary Uhr (1844-1903), who was born in Canada to Johann Uhr and Margaretha Paul Uhr. Together, they had seven sons and five daughters:
Liebel died March 11, 1905, one of Erie's best known citizens, at the family residence, 2316 Peach Street Erie, Pennsylvania. Liebel had been sick for over a year. His wife, Mary Liebel died a little more than year before him in 1903. Liebel’s funeral took place at St. Joseph's Church< and he is interred next to his wife in Trinity Cemetery in Erie.
Liebel was described as "an enterprising and progressive citizen and did much for the southern and southwestern end of the city." Additionally, it was said that "he was a man who made friends quickly and always retained them." He was a charter member of Catholic Mutual Benevolent Association ("C.M.B.A.") Branch No. 9 and also a member of the P. H. C. and the Erie Maennerchor, a German singing society and social club founded in 1871. In the final years of his life, Liebel engaged in the real estate and insurance business.
