A baby named Thaddeus Daniel Pierce was born on July 26, 2025, yet his embryo was actually frozen way back in May 1994. That was more than 30 years ago. This makes Thaddeus the world’s oldest baby to be born from a frozen embryo.
Linda Archerd, 62, and her then-husband underwent in vitro fertilization, or IVF, in the 1990s. They had four embryos created in 1994.
One of the embryos was transferred to Archerd, and she gave birth to a daughter, who is now 30 and mother to a 10-year-old. The other embryos were frozen in liquid nitrogen at a temperature of about -190 degrees Celsius.
The baby’s parents Lindsey and Tim Pierce, residents of Ohio, have been struggling to have a baby for several years. Years later, Linda decided to donate her frozen embryo, and it was adopted by Lindsey and Tim Pierce.

Lindsey Pierce recounted that, “We had a rough birth, but we are both doing well now. He is so chill. We are in awe that we have this precious baby.”
They had the embryo implanted in December 2024, and nine months later, baby Thaddeus was born, healthy and thriving.
This incredible birth breaks records and showcases how advances in fertility technology—and the miracle of embryo freezing—can help families create life even decades later.
Lindsey lovingly said their son is ‘so chill,’ and the whole family is amazed to have this special miracle baby—who actually has a genetic older sister born 30 years ago.
Thaddeus’s story is a beautiful reminder that science can preserve life in ways we could hardly imagine. It’s a true headline moment for reproductive medicine and an inspiring story of hope for many families.
