For the wife of Harry Wells of Earth-2, see Harrison Wells's wife.

"And what would you call these laboratories?"
"Well, we, Tess Morgan, would call them the 'Technological Engineering Scientific Studies,' or T.E.S.S., for short."
"Well, that is very, very sweet. But how about... 'Scientific and Technological Advanced Research Laboratories' or S.T.A.R. Labs, for short? Because in the vast night sky, you, Harrison Wells, are the only star I see.
—Tess Morgan and Harrison Wells[src]

Tess Morgan (died April 16, 2000)[1] was a scientist and the fiancée of Dr. Harrison Wells.

On April 16, 2000, Tess discussed with her fiancé about his dream of opening a laboratory free from government connections and business interests. While Harrison wanted to name the laboratories after her, she instead coined the name Scientific, Technological, and Advanced Research Laboratories, or S.T.A.R. Labs. Tess and Harrison were murdered by Eobard Thawne on that same day.


Original multiverse[]

Early life[]


Harrison and Tess

In the timeline of Earth-1, Tess Morgan and her fiancé, Dr. Harrison Wells, lived in Starling City,[2] and they planned to get married at some point.[3] In 2000, Harrison had an idea for a laboratory and discussed this concept with Tess while on a date at the beach, which made her smile. Harrison suggested T.E.S.S. as a name, to which Tess responded by suggesting S.T.A.R. Labs. Unknown to them both, Eobard Thawne was watching from behind.[2]


Eobard killed Tess and her fiancé in a car accident later that night as part of his plan to get Harrison's likeness and become him to make the particle accelerator launch years earlier.[2]

New multiverse[]

In the timeline of Earth-Prime, Tess's life presumably played out the same. Around 1996, she and Harrison got together.[4] Tess and Harrison were still murdered by Eobard, but Harrison would be resurrected moments afterward.[5]

Harrison used his new abilities to travel back and relive the four years he and Tess had spent together over and over. It's unknown whether she was made aware of this or not.[4]

Sometime in 2000, Harrison was watching television and called out to Tess and mentioned that President Bartlet had just mixed up meds. By that point, they were living in a house by the Starling City Beach.[6]


Like her fiancé, Tess was a very kind and caring person. She was shown to be very humble as S.T.A.R. Labs was going to be named after her; but Tess came up with the former name.[2]


  • Genius-level intellect/Master scientist: Tess was far more intelligent than Harrison Wells, a recognized genius himself. Her insight allowed her to finish research and development in a fraction of the time it would take her fiancé to finish.[7]


The Flash[]

Season 1[]

Season 7[]


  • In "The Flash is Born", Joe West states that Harrison and Tess were research partners in Maryland. However, this is seemingly retconned in "Tricksters", which places them in Starling City shortly before their deaths.
  • In "The Man in the Yellow Suit", Cisco Ramon stated that the "accident" that killed Tess occurred before Christmas. However, this was seemingly retconned in "Who is Harrison Wells?", in which a photograph from the night of the car wreck was seen dated April 16, 2000.
  • In "Tricksters", Eobard believed Tess and Harrison founded S.T.A.R. Labs in the year 2020 and saw their new company in its prime. They created the particle accelerator, and likely survived the explosion; however, unknown to Tess and Harrison, the unknown energies released from the particle accelerator explosion created many meta-humans, including Barry Allen/The Flash.[2]
  • In a deleted scene from "Fast Enough", Joe questions Eobard about how he managed to pretend to care about Tess. Eobard reveals that stealing Harrison's likeness, also took Harrison's memories, thoughts and feelings, thus aching with real love for Tess who Eobard never knew and ultimately killed.
  • Due to Randolf Morgan on Earth-19 sharing surnames with Tess, and a close relationship with H.R. Wells, Randolf could possibly be a gender-bent counterpart of Tess.[8]
  • It is heavily implied that Tess is the Earth-1 doppelgänger of a woman from Earth-2 who is Harry Wells's wife and Jesse Wells's mother. When Jesse hears her mother's voice through Harry's memories, her mother says "Because, in the vast night sky, you are the only star I see."[9] This phrase was first spoken by Tess to Earth-1 Harrison and is how S.T.A.R. Labs' name came to be.
