The Detmold Child, from Peru, dates to 4504AAC/AAAA4457 B.C. It was about 10 months old when it died, naturally mummified in the H๏τ, arid desert environment.

It is a baby mummy found in the Andes of Peru. It is currently one of the oldest mummies in the world: 6420 years old in a good state of preservation. He was named The Detmold Boy by his owners Lippisches Landes museum in Detmold, North Rhine-Westphalia, Germany.

Originally, the mummy was owned by the Völkerkundliches Museum (Ethnological Museum) in the city of Witzenhausen. After an affection for mold was recognized in the mummy, it was donated to the Lippisches Landes museum Detmold, where it was professionally preserved.

In 2010, the mummy was examined in the context of the German Mummy Project and the cultural historical significance of this object was realized.

Officials at the Lippe State Museum in Detmold, Germany, revealed that the Detmold boy died at the age of eight to nine months after suffering from a rare congenital malformation of the heart, known primarily as Hypoplastic Left Heart Syndrome (HLHS), a condition with parts of the left side of the heart are not fully developed.

The syndrome combined with the contracted pneumonia had led to the death of the baby. The boy was also found to be deficient in vitamin D and had an abnormal cone-shaped skull. The body had been covered in linen and buried with an amulet hung around its neck, a CT scan revealed.

The Detmold child was on display at the California Science Center in Los Angeles, California, along with 45 other mummies and 95 different artifacts.
