Harnischfeger Corporation, known for its mining equipment under the P&H brand, has a rich history dating back to its founding in 1884. The company was established by Henry Harnischfeger and Alonzo Pawling as the Pawling & Harnischfeger Machine and Pattern Shop in Milwaukee, Wisconsin. Henry Harnischfeger, born in 1855 in Salmuënster Kreischlichtern, Germany, emigrated to the United States in 1872. He initially worked in various trades, including as a locksmith and machinist, before partnering with Pawling.

The partnership initially focused on creating wood patterns and small components for other firms. In 1887, they rebuilt an overhead traveling crane for the E.P. Allis Company, leading to their specialization in manufacturing cranes. This success allowed P&H to develop their product line further, eventually expanding into earth-moving equipment by 1912. They introduced innovations such as the first gasoline engine-powered dragline and shovel-type excavators, which significantly impacted the mining and construction industries.

Harnischfeger Corporation became a world leader in mining equipment, known for its reliable and productive machinery. The P&H brand remains synonymous with high-quality mining equipment, supporting cost-effective mining operations globally.

Henry Harnischfeger passed away in 1930, but his legacy lived on through the company's continued innovations and expansions. Today, Harnischfeger Corporation's history is a testament to its significant contributions to industrial and mining equipment manufacturing.
