Thaddeus Daniel Pierce, known as the world’s “oldest baby,” was born on July 26, 2025, from an embryo that had been frozen since 1994. Originally conceived through IVF by Linda Archerd, the embryo was one of four—one became her now 30-year-old daughter, while the remaining three were frozen for over three decades. Following a divorce, Archerd chose to place the embryos for adoption, ultimately selecting Lindsey and Tim Pierce as the adoptive parents. The embryo transfer was carried out by Dr. John Gordon at a faith-based fertility clinic. Thaddeus is believed to be the oldest embryo ever successfully brought to term. His name, Thaddeus, adds to the vintage appeal—it reached peak popularity in 1918 at #307 and ranked 850th in 2024, making it a fitting choice for a child with such a historic origin.
