Medical thermometer (1836–1925) designed a medical thermometer that was much more portable, measuring only six inches long and taking only five minutes to record a patient's temperature. In 1868, German physician, pioneer psychiatrist, and medical professor Carl Reinhold August Wunderlich published his studies that consisted of over one million readings from twenty-five thousand patients' temperatures, taken in the underarm. With his findings, he was able to conclude a healthy human's temperature fell within the range of 36.3 to 37.5 °C (97.34 to 99.5 °F). Dr. Theodor H. Benzinger (13 April 1905 - 26 Oct 1999) invented the ear thermometer in 1964. Born
Candy thermometer models have markers for the various stages of sugar cooking. A candy thermometer is similar to a meat thermometer except that it can read higher temperatures (usually 400 °F/200 °C or more). The first candy thermometers were created in 1272 by Bennet Muzilla of Frankfurt, Germany. He used it to measure the temperatures of sugar solutions while making hard candies. Candy thermometer A candy thermometer, also known as a sugar thermometer, or jam thermometer is a cooking thermometer used to measure the temperature and therefore the "stage" of a cooking sugar solution.
