This is Part One of the Industry Primers audio program on insurance brokers, published by Latticework from MOI Global. It is the first of two audio programs that accompany the written primer on the insurance brokerage industry, and it is the story of the industry, told for a general audience. The account is built from documented scenes, with the people named, the dates given, and the participants quoted in their own words, many of them from their own interviews and talks. It assumes no background in insurance or finance and explains its terms, from a broker’s commission and a contingent commission to a book of renewals, a wholesaler and an underwriting agency, as they arrive. This episode is public.
The program runs from the brokers and notaries of London’s marine market in the 1570s to a takeover agreed in Sydney in August 2026, and from London and Chicago to Daytona Beach, Sydney, a German broker’s office and Delhi. Its people are the builders of the industry: Arthur J. Gallagher, who opened his firm in Chicago in 1927, and his grandson Pat Gallagher, who has run it since 1995; Henry Marsh and Donald McLennan; Patrick G. Ryan, who built Aon and then Ryan Specialty; J. Hyatt Brown, who bought his father’s agency on a note, and his son Powell Brown; David Howden, who started a London broker in one room in 1994 and shares its ownership with his colleagues; Robert Kelly, who co-founded the Steadfast network in Sydney; Lars Mesterheide of MRH Trowe in Germany; and Yashish Dahiya, who co-founded PolicyBazaar in India. It follows how a broker’s clients stay with the people who serve them, and how the builders who gave those people a share of the firm, through stock, partnerships and networks, built the best records.
Part One stands on its own. It tells how the industry took its present shape, from the London houses that American brokers acquired one after another to the private-equity buyers who bid up the price of small agencies. The economics of the business, and the companies as investments, are the subject of Part Two and of the written primer. The records it gives are total returns with dividends reinvested, each stated with its window and its benchmark.
The program runs in twenty sections:
Those People Who Sell. Arthur J. Gallagher, back in Chicago in 1920 with a battlefield commission won in France, keeps the books at a brokerage, learns that the money is made by the people who bring in the clients, wins the partners’ leave to try it while still doing the books, and in 1927 opens Arthur J. Gallagher & Co. with one woman beside him.
Thirty Brokers and Sixteen Notaries. In the 1570s a royal patent gives Richard Candler the registration of every insurance policy in the City of London, over the petitions of a trade a historian counts at about 30 brokers and 16 notaries; in 1774 Lloyd’s moves into the Royal Exchange, Henry Willis applies to join it in 1841, and by 1912 Willis, Faber & Co. is the Titanic’s broker, its hull claim of GBP 1m paid in full within 30 days.
Three Men and One Railroad. Marsh traces its origins to a fire agency opened in Chicago in October 1871, the month of the Great Fire; Henry Marsh persuades U.S. Steel in 1901 to insure its own fire risks with his firm managing the fund, Marsh, Donald McLennan and Daniel Burrows combine at the end of 1904 rather than compete for one railroad’s account, and the same year a New York court holds that an agent’s expiration register belongs to the agent, so an agency’s book of renewals can be sold.
The Art of the Leverage. In 1966 the founder’s grandson, Pat Gallagher, sent across Chicago’s Loop after eighth grade to collect blank policy forms, comes back empty-handed until his boss, his grandfather’s first employee, asks the Travelers on the telephone whether she should place her clients with it or with the Hartford; in 1984 the firm lists its shares, and Robert E. Gallagher writes its 25 tenets on a single page, the first defining it as a sales and marketing company.
The Car Dealer’s Son. Patrick G. Ryan, a car dealer’s son from Wisconsin who sold memory books to students at Northwestern, goes into life insurance in 1959, moves to fire and casualty, sets up in 1962 what the Automotive Hall of Fame credits as the first finance and insurance department in a car dealership, and in 1964 founds Ryan Insurance Group on what he calls multiplying yourself through others.
Bought on a Note. In 1961 J. Hyatt Brown takes over his father’s Daytona Beach agency, about USD 61,000 of revenue, USD 1,400 of profit and eight people, for USD 75,000 on a note at 10 percent for his parents’ lifetimes, and with the Cook Agency of Bunnell in 1965 he begins to grow it by acquisition.
Not a Crook. Robert Kelly learns how insurance is distributed on a six-week tour of the Pacific islands, starts a brokerage in Sydney, loses it in 1974 when AUD 43,000 of life commissions is clawed back in a single month, drives a cab and repays his debts over about seven years, and is forgiven by the rugby league coach Jack Gibson, whose wrecked Cadillac was not covered, with a charge to do for other people what Gibson had done for him.
Great Salespeople. Brown & Brown doubles its revenue from 1980 to 1982 without an acquisition while its margin falls from 16 percent to 8, a consultant’s verdict leads in 1983 to offices run as profit centers and measured every month, and in April 1993 the merger with the listed Poe & Associates of Tampa gives its employees and its sellers shares they can own.
A Gaelic Word. In August 1982 W. Clement Stone’s insurer, Combined International, acquires Ryan Insurance Group for USD 133m and makes Pat Ryan its chief executive; renamed Aon, a Gaelic word for unity, in 1987, it takes over Bain Hogg, Alexander & Alexander and Minet in the 1990s, and USD 1,000 invested in Combined in August 1982 became about USD 13,600 by Ryan’s handover in April 2005, about 12 percent a year with dividends reinvested.
Covered Through Lloyd’s of London. During the Montgomery bus boycott of 1956 the Atlanta broker Theodore Martin Alexander finds the carpools cover at Lloyd’s after local agents cancel it, as Martin Luther King Jr. confirms in a letter of February 8, 1957, and from 1980 to 2019 the American brokers acquire the great London houses, Marsh & McLennan ending with Jardine Lloyd Thompson at GBP 19.15 a share, the largest acquisition in its history.
The Dog Was a Receptionist. David Howden, who started at 16 fetching bacon sandwiches at a London broker and saw his employers bought by other firms one after another, opens Howden Pangbourne on November 16, 1994 in a room in Pinnacle House with two colleagues and his dog, Flight, and in 1997 wins Spear Gulland away from Willis by offering its owner shares instead of money.
Forty-Three Islands. Robert Kelly persuades 43 small brokerages to bargain with the insurers as one, Steadfast opens in April 1996 and lists in August 2013, and with dividends reinvested AUD 1,000 put in on its first trading day became about AUD 6,100 by October 21, 2026, against about AUD 2,900 in the fund that tracks Australia’s 200 largest listed companies.
Part of Our Business Model. Eleven weeks after Jeffrey Greenberg calls contingent commissions part of Marsh & McLennan’s business model, Eliot Spitzer sues the firm on October 14, 2004, alleging that it steered clients to the insurers that paid them; its shares fall 47.8 percent in four sessions, Willis renounces the payments first and regains its price by November 10, and Marsh & McLennan, which settled without a ruling on the allegations, regains its pre-suit close only on October 25, 2013.
Not Going to Compete With You. After handing Aon to Greg Case in April 2005, Pat Ryan founds a wholesale broker that serves retail brokers and never their customers, opens it on July 1, 2010 with more than USD 400m of his family’s money committed ahead of the business, and lists Ryan Specialty at USD 23.50 a share in July 2021; by Ryan’s last day as chief executive, in 2024, its shares had more than doubled with dividends reinvested, about 32 percent a year.
The Biggest Small Company. Howden co-founds the underwriting agency DUAL in Madrid in 1998, takes outside money only as minority stakes, from 3i in 2008 to Hg in 2021, decides after Jardine Lloyd Thompson’s sale in 2019 to move faster, and in August 2025 opens an American retail broker led by four former leaders of Marsh’s Florida business; Business Insurance’s ranking of 2026 puts Howden ninth in the world, with about USD 4bn of brokerage revenue.
Five Meters of Fax Paper. Lars Mesterheide and his partners write a new liability wording for German roofers over a weekend, mail every roofer in the country through a trade paper and come back to a five-meter roll of fax replies and 180 roofing firms under mandate; by mergers of equals the firm becomes MRH Trowe, and when an investor comes in at the end of 2020 it takes a minority.
Sixty Percent More. In 2008 Yashish Dahiya tells Sanjeev Bikhchandani that he is paying 60 percent more for his car insurance than he needs to, finds a quote about 40 percent lower in half an hour, and wins INR 200m from Info Edge for 49 percent of PolicyBazaar; the company lost money for 15 years before turning a profit, and by Dahiya’s count it had 11,156 rejected claims reconsidered and paid in a single year.
A Piece of the Rock. From the 1993 merger Brown & Brown grows to 303 profit centers in 43 states by 2020, USD 1,000 put into Poe & Brown at the merger became about USD 14,300 by the founder’s handover in 2009, against about USD 2,850 in the S&P 500, and on August 1, 2025 the company completes Accession, its largest purchase, for USD 9.825bn.
Accumulating Brainpower. Gallagher acquires 48 brokers in 2024 and 33 in 2025, most of them small, at a weighted 9.4 times a year’s operating profit in the first quarter of 2026, completes AssuredPartners for USD 13.45bn, and USD 100,000 put into Gallagher at the end of 1994 became about USD 8.1m by October 21, 2026, against about USD 3m in the S&P 500, both with dividends reinvested.
Plan Your Work. The summer internship that Pat Gallagher’s father created in 1965 for one young man had four interns in 1972, Pat Gallagher among them, and about 600 in 2026; as the firm his grandfather started nears its hundredth year in 2027, he recalls the advice his grandfather gave him on his first day of work.
