# Early Life

## Childhood

Leonard Leakey Simmons was born in Ashburton, Devon, England to Cindy Madison and Richard Simmons on May 17, 1358. When he was twelve, in 1370, along with his sister, Jemma, and his parents, Leonard moved to Cambridge, United States. Wanting to fit in, Leonard was determined to lose his British accent, and accomplished this to the extent that his friends were always shocked to discover he was actually born in England. He took advanced placement classes throughout his entire education and graduated at 16, in 1374. After high school, Leonard attended Princeton University, and completed two doctorates, by the age of 20, in 1378. Leonard, and his sister, Jemma were quite close when they were young, but he moved away after graduating, and they didn't have much contact, aside from family reunions and some holidays, due to both their dedication to their respective sciences. Leonard's youngest sister, Amelia, was born after he moved away from home. They remained somewhat close through phone calls and emails even after she moved to France to complete her Bachelor and PhD.

Leonard was often sickly child, having conditions including: lactose intolerance, asthma, myopia, car sickness, migraines, sleep apnea, pollen allergies, ear infections, and a genetic predisposition to heart disease from his father’s side.

When he was 7, he started learning to play the cello.

## High School

In school, as he was often the youngest in his class and had a hard time fitting in due to his intelligence and his age, he was often the victim of bullying. He would get stuffed into lockers or into his own cello case. Also, not helping his case, his name includes the word ‘nerd’ in it.
He joined his school’s debate club, and was quickly made the club president.
It was always assumed that Leonard would become a scientist, given the professions of his parents and the IQs of his whole family, but he claims what really inspired him to pursue science was watching Professor Proton.
He stops growing in 8th grade, ending up at a height of 5 ft 5, which is often a source of embarrassment for him, though he is proud that he is 1 ¼ inches taller than his friend Howard.

## University

He chose to study Experimental Physics at Princeton University.

# Mid Life

## Career

After graduating from Princeton University, Leonard gets a job as an experimental physicist at CalTech. Over the years, he has been published in many peer-reviewed journals. Some of his work has included: conducting classified government research on military rocket fuel capable of generating 8000 kN of thrust, high powered lasers, Bose-Einstein condensates, fundamental tests of quantum mechanics, cosmic radiation, and dark matter. He has been honoured with the Newcomb Medal.
Alongside Sheldon, Leonard co-authored a paper titled “Paradoxical Moment-of-Inertia Changes Due to Putative Super-Solids” to be presented at an Institute for Experimental Physics topical conference on Bose-Einstein condensates. The findings of the paper contained how temperatures approaching absolute zero cause a solid to become a super-solid - a previously unknown state of matter, and how the moment of inertia changes.
When studying the soft component of cosmic radiation at sea-level, Leonard designed an experiment using a helium-neon laser. He procured a large government grant to see if high-powered lasers could be used to knock out incoming missiles. He also worked on a front-projected holographic display combined with laser-based finger tracking.
His research into dark matter was rendered useless by Dr. David Underhill’s observations of high-energy positrons, which were the first conclusive evidence for the existence of galactic dark matter. Together, the two scientists examined the radiation levels of photo-multiplier tubes for a new dark matter detector. Leonard attempted to replicate the dark matter signal found by the Italians and has grown isotopically pure crystals for neutrino detection and with Howard, built a multi-wire proportional counter for detecting cosmic particles.
Leonard has also carried out a series of anti-proton decay experiments with negative results. These experiments consisted of twenty thousand data runs and no statistically significant results.

He also conducted tests of the Aharonov-Bohm quantum interference effect, which reached an interesting point when examining the phase shift due to an electric potential, where he set up the voltages using tunnel junctions.

Leonard was invited to join Dr. Stephan Hawking’s team which was sent on an expedition to the North Sea to test hydrodynamic simulations of black holes. He spent four months looking into the possibilities that one could find the equivalent of Unruh radiation in a large body of water, as was suggested by the similarities of the equations of general relativity and hydrodynamics.

In 1392, Leonard begins writing a book about a physicist solving amurder at the CERN collider in Switzerland.

In 1393, Leonard is given a co-lead position on a photo-entanglement project.

## Friends

In 1377, Leonard moved to Pasadena, California and began sharing an apartment with Sheldon Cooper. He also met Howard Wolowitz and Raj Koothrappali, through his work at Caltech. The four became a tight-knit group and spent a lot of time together, mostly at Leonard and Sheldon's apartment.

## Family

### Marriage

On September 24, 1381, Leonard met Penny Baird and instantly fell in love with her. Penny soon became integrated in their tight-knit group, and spent almost as much time in the guys apartment as she did in her own. The next year, Leonard finally gathered up the courage and ask Penny out on a date. She agreed and they went out on a date, but broke up shortly after because Penny thought that he would only date a girl with a college degree. Over the next year, Leonard had two other girlfriends, Stephanie and Leslie, but neither relationship lasted very long. In 1383, Leonard and Penny give it another go, and while they had some trouble being more than friends, they eventually started a stable relationship. The relationship lasted a couple months, but after Leonard admits to Penny for the first time that he loves her, Penny freaked out. Due to her commitment issues, the two once again broke up. After another year had passed, the two decided to try again, “ beta testing” to ensure that they didn't face the same problems as last time. After they had been dating for about 7 months, Leonard decided to ask Penny to marry him. Penny turned him down, claiming that she is not ready for that sort of commitment yet, but still wants to keep dating.

 In 1387, Leonard went on a North Sea Expedition as a part of his work. Over the next year, their relationship got pretty serious, and by the end, Penny proposes to Leonard, which he accepts, revealing that he had been carrying around a ring for her for many years. Leonard and Penny each had proposed to each other 3 times before they finally could agree and accept each other. On May 1 1388, Leonard and Penny go to Las Vegas to get married. Because of the surprise elopement not sitting well with all their friends and family, they decide to have another ceremony to renew their vows with everyone attending on September 19, 1390, which is officiated by Bernadette Robbins. After getting married, Penny moves in with Leonard in Apartment 4A.

### Parenthood

 In 1391, Leonard is chosen to be the best man at his former roommate and best friend, Sheldon’s, wedding. In 1393, Leonard is made co-lead on a new experimental physics project. On May 10, 1393, Penny and Leonard discover they are pregnant with their first child. Jessie Simmons was born on 1393, followed by her two sisters, Vivian and Lexi in 1397 and 1399 respectively. The not so small family crowded into the Apartment 4A for the first couple years after Lexi was born, but soon Leonard and Penny realized that they needed to move somewhere with a couple more rooms if they were to have 3 teenage girls living there. The 3 girls took after their father with their love of science, and all three had high IQs.

## Grandchildren

As Leonard had 2 sisters and 3 daughters, he was not surprised that all of his grandchildren (Sam, Graciela, Catalina, Eloise, Gracie, and Makayla) were all girls as well. By the time the last granddaughter was born, he had long given up hope of another male being born into his bloodline.
