Let's all give a celebratory happy birthday to Carl Paul Gottfried Linde! Although you may not know who this German engineer was, your daily life is indeed affected by him. Born in 1842, Linde developed a process to liquefy gases that lead to the creation of the modern refrigerator. After his research and proposal for the technology of refrigeration was published in a Bavarian Industry & Trade Journal, he was approached by Europe's top breweries that were investigating ways of maintaining beer's temperature for longer periods of time. In 1873, the first fridge was installed and declared a huge success. Linde continued his studies and variations on his ideas are still practiced today. So when you open your fridge today remember Linde, without him who knows how beer - or anything else - would have been kept cold!
