Pran Tainer

Doctor Pran Tainer was an Atrean geologist and husband of Doctor Juliana Tainer.

In 2370, the Tainers discovered that the magma on their homeworld Atrea IV was cooling, which posed a significant threat to the continued habitability of the planet. The starship USS Enterprise (NCC-1701-D) was sent to assist in finding a solution to this problem. While investigating, Juliana was involved in an accident which revealed that she was, in fact, a Soong-type android constructed by Dr. Noonian Soong, Data's creator. She had been created in the image of the real Juliana Tainer. Pran was unaware of her true nature.

The Tainers developed a technique known as ferroplasmic infusion which would relieve the problem on Atrea IV for centuries.
