Born in Germany in 1874, Philip Haas had at least 10 siblings. The family emigrated to the US in 1888, settling in Dayton. Soon after, Haas became an apprentice to a plumber, starting his career.
Philip did not invent the toilet, however he made many improvements to it that are still in use today, turning a formerly unreliable product into its modern equivalent. Over the course of his career, Hass applied for 31 plumbing and/or toilet related patents.
