Reference excerpt

Lionel Luthor is a fictional character portrayed by John Glover in the television series Smallville. The character was initially a special guest in season one, and became a series regular in season two and continued until being written out of the show in season seven. The character returned to the show in season ten again in a special guest role as a parallel universe version of the character. In Smallville, Lionel Luthor is the father of Lex Luthor (Michael Rosenbaum), and founder and CEO of LuthorCorp. Lex Luthor's father was first introduced in Superman comics by Jerry Siegel in 1961 and has since appeared in other Superman-related media under different names. Smallville is the first appearance in which the character has been an intricate part of a Superman adaptation. Series developers Alfred Gough and Miles Millar created Lionel Luthor for Smallville to provide an antithesis to the parenting style of Jonathan Kent (John Schneider) and Martha Kent (Annette O'Toole). In the DC Comics, Lex Luthor's father was originally named Jules Luthor, but later was renamed Lionel Luthor some time after Smallville. He debuted in Superman's Girlfriend, Lois Lane #23 (February 1961) and was created by Jerry Siegel and Kurt Schaffenberger. During the story of Smallville, Lionel evolves from being a nemesis of Clark Kent (Tom Welling) who develops multiple schemes to uncover Clark's secrets, to becoming an ally who eventually dies to protect Clark's secret from his own son. Lionel has a strained relationship with Lex and regularly tries to test him. He attempts to develop a romantic relationship with Martha Kent after inadvertently causing the death of Jonathan Kent, helping her advance toward the United States Senate. A parallel universe version of the character is later introduced in the show's final season who serves as Clark and his allies' adversary and plays a pivotal role in bringing Lex back from his presumed death. Lionel's development from a main antagonist to an ally was difficult for the writers who felt the character's arc failed to achieve the status they wanted. Although they continued with the story arc, Lionel returned to using deception to protect Clark rather than exploit him. He is characterized as a sinister character who tried hard to further his own ambitions. Lionel's relationship with his son has been likened to that of Harry Osborn and Norman Osborn from Spider-Man comics.

Role in Smallville

Earth-1 version In 1989, Lionel visits Smallville to buy the Ross Creamed Corn company immediately before a meteor shower occurs. Twelve years later during season one, Lionel exiles his son Lex Luthor (Michael Rosenbaum) to Smallville to run LuthorCorp's local fertilizer plant as a test. When Lex makes a profit for the first time in years, Lionel closes the plant and blames Lex's poor managerial skills. Lionel later confronts his son at the Luthor mansion when Lex tries to orchestrate an employee buyout to save the fertilizer plant. When strong winds force debris to smash through the mansion, Lionel is pinned under a fallen support beam and Lex hesitates to save his father. In season two, Lex saves Lionel but Lionel loses his sight because of Lex's judgment to rush into surgery. Lionel is initially shown as blind until Lex and Lucas Luthor (Paul Wasilewski)—Lionel's illegitimate son—devise a plan to uncover Lionel's deception; it's revealed that Lionel was blind but that his eyes healed and he intentionally neglected to tell anyone so he could watch how they acted around him. Lionel is later aware of the Kawatche caves and tries to unlock the mysterious symbols there, to the dismay of Clark Kent (Tom Welling). Season three revealed that Lionel conspired with Morgan Edge (Rutger Hauer) to murder Lionel's parents and used the insurance money to fund LuthorCorp. Lionel has Lex committed to a mental institution, after Lex discovers what Lionel did. When Chloe Sullivan (Allison Mack) discovers the truth, her evidence is used to assist Lex in having Lionel arrested for the murder. It is also revealed that Lionel is hates Lex because he blames his son for the death of his youngest son Julian Luthor, although Lex took the blame to protect the true killer Lillian (Alisen Down), Lionel's mentally unwell wife. Lionel also learns that he has a terminal liver disease, which he divulges to Lex while awaiting arraignment. Lionel is sentenced to prison for his parents' murder in season four. Lionel attempts to switch bodies with Lex using a stone from Clark's homeworld of Krypton but Clark intervenes and Lionel switches bodies with Clark instead. When he and Clark switch back, Lionel discovers his terminal liver disease is healed. Lionel is released from prison by Genevieve Teague (Jane Seymour), and begins searching for three stones of knowledge. During this quest, Lionel falls into a catatonic state after being uploaded with Kryptonian knowledge. Lionel recovers in season five when Jor-El's artificial intelligence takes over his body to speak with Clark. Under Jor-El's guidance, Lionel begins helping Clark by making excuses for Clark's behavior and unexplained disappearances throughout seasons five and six. Season seven revealed that Lionel and three other wealthy families formed the secret society Veritas to protect an alien visitor known as the Traveler (Clark) and that Lionel murdered the other members. Lionel also has Clark kidnapped and tortured. Lex realizes Lionel has been covering up the Traveler's existence and kills him. Season ten reveals that Tess Mercer (Cassidy Freeman) is Lionel's illegitimate daughter fathered with Pamela Jenkins (Donna Bullock).

Worked examples

Example 1 — a first encounter with Lionel Luthor

Start with the simplest possible case. Write down what Lionel Luthor claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lionel Luthor before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lionel Luthor ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lionel Luthor

In research: Lionel Luthor appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lionel Luthor in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lionel Luthor is common in secondary-school and first-year university syllabi. It links to neighbouring topics Comics characters introduced in 1961, DC Comics businesspeople, Fictional characters from Kansas, so understanding it makes those chapters shorter.
In everyday life: Look for Lionel Luthor outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
