Peter Carl Goldmark is credited with the invention of the long-playing (LP) microgroove record, which he developed in 1948 while working at Columbia Records. Before the invention of the LP, records were limited to a playing time of around four minutes per side. Goldmark's invention used vinyl and a microgroove technology to increase the playing time of records to up to 30 minutes per side. This allowed for the development of the modern album format that we know today.    In 1948, Peter Goldmark, a Hungarian-American engineer and inventor, achieved a monumental breakthrough in the realm of music and audio technology. He is credited with the invention of the Long-Playing (LP) record. This innovative creation revolutionized the way people experienced and enjoyed recorded music. Before Goldmark's invention, music was primarily distributed on fragile and limited-capacity 78 RPM shellac records. Goldmark recognized the need for a more durable and versatile medium that could offer an extended playtime and improved sound quality. The result was the introduction of the vinyl LP record, which played at a slower speed of 33 1/3 RPM. The LP format allowed for longer playing times on each side of the record, providing artists with the opportunity to create cohesive albums rather than single tracks. This shift fundamentally transformed the music industry, paving the way for the concept of the "album" as a curated collection of songs. Goldmark's LP record not only increased the durability of records but also significantly enhanced the overall quality of recorded sound. Peter Goldmark's inventive spirit and technological prowess in introducing the LP record had a profound and lasting impact on the music industry, shaping the way artists produced and presented their music. His creation laid the groundwork for subsequent audio formats and continues to be celebrated for its pivotal role in the evolution of recorded music.
