Philip Ludwig "Louis" Breithaupt was a German-born tanner and politician in Ontario, Canada. He served as mayor of Berlin from 1879 to 1880. The son of Liborius Breithaupt, a tanner, and Catherine Goetze, he was born in Allendorf, Kurhessen, which today is a part of Germany. He received an ordinary education in Germany, and there he was partially trained as a tanner by his father, Liborius, who was the fourth generation of tanners in the Breithaupt family. Liborius relocated his family Buffalo, New York in November 1843, bringing Louis with him. Liborius, with Louis assisting him, opened a small tannery in Buffalo located on Seneca Street, which mostly processed sheepskins. This situation continued until 1851, when Liborius died, and Louis took over the business, continuing to operate it under the name "L. Breithaupt". In 1852, he took on a partner, Jacob F. Schoellkopf, a Buffalo financier who at the time was investing heavily in the tanning industry. Together they expanded the business and in 1855 they purchased another existing tannery in North Evans, New York. On a trip to Canada to buy sheepskins, Breithaupt met his future wife, Catharine Hailer of Berlin. She was the daughter of wheelwright Jacob Hailer, who was an early German settler in Berlin. They were married on 8 February 1853, beginning the process that would end with Breithaupt relocating himself to Berlin. His three eldest sons, Louis Jacob, William Henry, and John Christian, who would later become locally prominent in their own right, were born in Buffalo before the move, in 1855, 1857, and 1859 respectively. In 1857, Breithaupt opened a tannery in Berlin in partnership with his new brother-in-law, Jacob Wagner, who soon died in the next year of 1858. Breithaupt at first tried to manage the Berlin tannery from Buffalo, but was frustrated by the situation, and ultimately made the decision to relocate to Berlin and concentrate his business operations there. He did so in 1861, selling off his share in the business he had started with his father to Schoellkopf and focusing entirely on managing his Berlin tannery. Breithaupt quickly became a prominent local figure in Berlin. In 1862, he paid $10,000 for the construction of the three-storey American Block at the northeast corner of King Street and Queen Street. This multi-purpose commercial building contained storefronts along King Street which were rented out to merchants, as well as a hotel entrance and the entrance to his office and leather goods store along Queen Street. The upper floors were used for hotel rooms in what was known as the American Hotel, possibly due to Breithaupt's American origins. Some of the American Block's earliest mercantile tenants included Tyson's Grocery and a boot and shoe store owned by William Niehaus, both occupying King Street storefronts. In 1866, Breithaupt was elected to the Waterloo County council, and in 1867 his tanning business was prominently advertising the sale of sole leather, leather findings, and bookbinders' stock, among other goods, at his retail store on Queen Street within the American Block. He suffered a significant setback that year when his tannery was destroyed by fire, but he rebuilt and continued, and was elected as deputy reeve of Berlin. His tannery suffered another fire in 1870, but was again rebuilt. Breithaupt continued his investment in Berlin real estate and began paying for the construction of houses, such as rental properties built in 1872 and 1876, as well as Sonneck House, his own suburban home, which was built in 1874 in Italianate style and which prominently featured stained glass work. He was elected as a county councillor again in 1876, and reached the zenith of his political career when he was elected as mayor of Berlin in 1879. In 1880, while still in office as the mayor of Berlin, Louis Breithaupt died. He is buried in Kitchener's Mount Hope Cemetery. His three sons co-managed the Breithaupt leather company after his death, and would continue under family management and ownership until its sale in 1967.
