"Catherine Langford was more than just kind and generous. She had a gift of an endless, open-minded, child-like curiosity. She saw the world not for what it was, but for what it could be, and she saw potential in people that others failed to recognize. Like her father before her, her contributions to science have changed the world more than most people know. I, for one, have no idea where I would be today if I'd never met her. She changed my life in more ways than I ever could have imagined."
Daniel Jackson at Catherine Langford's funeral.[src]

Catherine Langford was the daughter of the archaeologist Professor Paul Langford. She dedicated her life to unraveling the mystery of what would become known to Earth as the Stargate, a device she witnessed her father discover in Giza in 1928.

Much of Catherine's life was influenced by her father's discovery of the Stargate, on the Giza plateau in 1928 when she was a young girl. It was at the Stargate's excavation site where she discovered an Eye of Ra medallion - a deeply cherished item that she would wear for the rest of her life. (Stargate)


Catherine and her father have been studying the Stargate for some time, but up to that point they had been unsuccessful in learning what it is or what its purpose is. During this time, she had met James Beal, a captain in the British Military, at a market and was involved in a romantic relationship with him. The two of them (along with an Egyptian lieutenant in the British army, Wasif Alabu Khan) later went through the Stargate to rescue Catherine's father after he was kidnapped by Nazis. After preventing the Nazis from getting alien tech, the goa'uld Aset, who was ruling the planet at the time, erased Catherine and her father's memories of the experience and planted the seeds of the Stargate program in Catherine's mind. Then they were sent back to earth, with Beal getting killed in the process and Wasif being brainwashed and made one of Ra's guards. Back on earth, when the British government asked Catherine and her father if they knew Captain Beal's location, Catherine only remembers meeting him once at the market. (Stargate Origins)

Catherine as a twenty-one-year-old woman in 1945.

Catherine's father and her fiancée, Ernest Littlefield, did experiments on the Stargate in 1945. Catherine's father told her Ernest had died in an accident, but in reality he traveled through the mysterious ring to another planet and was presumed lost. (SG1: "The Torment of Tantalus")



Catherine Langford in 1969.

In 1969, Catherine received a brief visit from two strangers, one of whom claimed to be the son of Heinrich Gruber, her father's partner in the original dig in Giza and researcher on the Stargate in 1945. She was able to tell her visitors where the Stargate was currently being stored. In reality, the visitors were Captain Samantha Carter and Dr. Daniel Jackson who, along with Teal'c and Colonel Jack O'Neill, had been accidentally transported back in time. It's possible that Jackson and Carter's visit prompted Catherine to begin pressing the military to reopen its research on the Stargate. By this time, her father had died. (SG1: "1969")

Catherine Langford in 1996.

In 1996, she hired Daniel Jackson, this time fully aware of who he was, to re-translate the texts discovered with the strange ring. It was Daniel who discovered that the artifact was called a Stargate. Later, through linking star signs with glyphs on the object, Daniel made the intuitive leap that made it work for the second time, which was the first time as far as Catherine or anyone else involved in Project Giza knew. She gave Daniel the Eye of Ra medallion for good luck when he went through the gate. Catherine said that she had no desire to travel through the 'Gate herself – now that she knew what it was for and how it worked, she felt "complete".

Although Daniel remained behind on the other side of the Stargate, he sent her medallion back with O'Neill, asking him to tell Catherine "it brought [him] luck." (Stargate)


In 1997, Daniel discovered the Stargate had been successfully activated in the 40s and went to visit Catherine for answers. She was pleased to see Daniel, and confirmed for the first time that the Eye of Ra had been returned to her. Upon realizing that Littlefield might still be alive, she accompanied SG-1 to the planet Heliopolis. Once there she was reunited with Ernest and they traveled back to Earth together. (SG1: "The Torment of Tantalus")


Catherine died in 2005. Daniel gave a eulogy at her funeral that was well received by her niece, Sabrina Gosling. Sabrina said that Daniel was like a son to Catherine, and returned the Eye of Ra medallion to him. Gosling later arranged for Daniel to receive the rest of his inheritance from Catherine, which, much to his shock, turned out to be her entire collection of artifacts. Catherine's legacy turned out to have one more boon, as her collection ultimately led to the discovery of a Zero Point Module which was instrumental in saving the Atlantis expedition. (SG1: "Moebius, Part 1")
