Long before “Life’s Good” campaigns, the Koo story sat inside Joseon‑era genealogy. Koo In‑hwoi traced his line back to Gu Seong‑ro, an officer who accompanied Yi Seong‑gye during the Wihwado Retreat that founded the Joseon dynasty, and to Gu Sa‑min, uncle of Queen Inheon.[page:46] In modern terms, he was born into the Neungseong Gu clan — not royalty, but close enough to the old court to carry status in rural Jinju.

After finishing secondary education at Central Normal Higher School in Seoul in 1924, he returned home and tried his hand at business: heading a village cooperative, then opening a store in Jinju with his younger brother Koo Chul‑hwoi in 1931.[page:46] The shop hemorrhaged money and failed, forcing him to mortgage family property to secure fresh loans — an early case study in chaebol risk appetite on a village scale.[page:46]

In the 1930s, Koo shifted from retail to representation, running a Dong‑A Ilbo branch office in Jisu while expanding his trading activities.[page:46] By 1941 he was prosperous enough to quietly fund the Korean Provisional Government in Shanghai, echoing an earlier donation from his father to independence fighter Kim Ku — a reminder that the Koo balance sheet was tied to nationalist politics as well as commerce.[page:46]

After liberation, he moved to Busan and began importing charcoal, becoming the first Korean firm to receive trade approval from the U.S. Army Military Government.[page:46] Around this time, a relative of his wife, Huh Man‑jung, arrived with his son Huh Joon‑gu, proposing an investment if Koo would train the boy in business; this bargain forged the Koo–Huh partnership that would define LG’s ownership structure for decades.[page:46]

Acting on advice from his younger brother Koo Jung‑hwoi, In‑hwoi jumped into cosmetics manufacturing in the late 1940s.[page:46] In 1947 he founded Lak Hui Chemical Industrial Corporation, whose flagship product was a face cream branded “Lucky” — priced high for post‑war Korea but embraced for its quality ingredients, to the point that early production runs sold out.[page:46]

Lucky cream’s early success exposed a basic manufacturing flaw: metal lids leaked and broke, generating waves of returns.[page:46] Koo’s answer was to import an unfamiliar material — plastic — and apply it not just to cream lids but to hairbrushes, washbowls and, eventually, toothbrushes and household goods, turning Lak Hui into Korea’s first major plastics player.[page:46]

In September 1952, Koo opened a plastics plant in Busan and launched plastic hairbrushes, which became an instant hit and forced him to add more machines within two months to meet demand.[page:46] The product line quickly expanded to toothbrushes and washbowls, embedding the Koo name in Korean bathrooms and kitchens long before it appeared on televisions.[page:46]

In 1953 he formalised the venture as Lak Hui Industrial Co. Ltd., and in 1958 he founded Goldstar to enter electronics.[page:46] By 1959, Goldstar had produced Korea’s first domestically made radio, followed by phones, fans, air conditioners, televisions and refrigerators — consumer hardware that, alongside Lucky’s toothpaste, soap and synthetic detergents, would later be folded into the LG brand architecture.[page:46]

Official records list Koo Cha‑kyung as In‑hwoi’s son and successor in the business.[page:46] After In‑hwoi’s death on 31 December 1969 at his home in Seoul, Cha‑kyung took the helm and oversaw LG’s expansion through the 1970s and 1980s, further professionalising the group while keeping ultimate control inside the Koo line.[page:46]

Later generations — notably Koo Bon‑moo and Koo Kwang‑mo — continued the pattern: sons, nephews and adopted heirs rotating through key posts across LG Electronics, LG Chem and financial affiliates, often in consultation or quiet tension with the Huh branch tied to LG Household & Health Care.[page:46] The result is a dual‑family chaebol that still presents itself as a single corporate brand, masking internal dynastic negotiations behind a unified “LG” logo.

In Korea, pedigree is not only a business concept but a genealogical one. In‑hwoi’s pride in being the 14th‑generation descendant of Gu Sa‑min and the 12th‑generation descendant of Gu Seong‑ro anchored the modern Koo fortune in a much older Neungseong Gu clan narrative.[page:46] That story links the LG founders back to the early Joseon state — a symbolic counterweight to the perception that chaebols are purely products of 20th‑century crony capitalism.

The family’s inclusion in “Koo family (South Korea)” and “Neungseong Gu clan” categories is more than taxonomy; it represents a deliberate branding of LG as a continuation of a long‑standing Korean lineage rather than a rootless corporate invention.[page:46] For a consumer‑facing conglomerate selling soap, screens and smartphones, clan respectability doubles as soft power.

Koo In‑hwoi died in Seoul on 31 December 1969 at the age of 62, just as Korea’s high‑growth decades were accelerating.[page:46] By then, the pieces of LG were in place: chemicals and cosmetics, plastics, electronics and media, all tethered to the Koo household and its allied Huh branch.

His passing did not provoke a public succession crisis; instead, the baton moved quietly to his son Cha‑kyung and then down the line, in keeping with the chaebol norm of hereditary corporate monarchy.[page:46] From the outside, the only visible change was a new signature on board resolutions; inside, the family web tightened as later generations sought to keep both ownership and management from drifting toward outside professionals.

Among Korea’s big families, the Koos occupy a specific niche: not as dominant as the Samsungs, but entrenched across everyday consumer life — from toothpaste to OLED panels — in a way few rivals match.[page:46] Their origin story, rooted in clan genealogy, failed shops, independence donations and a plastics gamble, gives LG a different texture from export‑heavy chaebols built purely on steel, ships or chips.[page:46]

As of the 2020s, Forbes tracks the “Koo family (LG)” as one of South Korea’s major billionaire clans, with wealth split across listed companies and private holdings.[page:46] The family’s challenge now is the standard chaebol test: how to hand power from founders’ grandchildren to great‑grandchildren without splintering control — and how to keep the “Life’s Good” brand from being overshadowed by the less photogenic reality of dynastic capitalism behind it.
