William Edward “Bill” Macaulay (Sept 2, 1945 – Nov 26, 2019) was an American investor and private-equity pioneer best known as the co-founder and longtime leader of First Reserve, a private-equity firm specialized in energy deals. He built a reputation as a low-profile but highly influential figure in energy buyouts and energy-sector investing. Wikipedia+1

Early life & education

• Grew up in the Bronx, New York. Wikipedia

Early career

First Reserve and rise

• In 1983 Macaulay co-founded First Reserve (with John Hill). Under his leadership the firm became one of the largest energy-focused private-equity managers in the world, raising many billions to buy, consolidate, and grow oil & gas and energy services companies. privateequitywire.co.uk+1

Philanthropy & public profile

• Donor to education: his major gift (commonly reported as $30 million) to the City University of New York led to the naming of the Macaulay Honors College. He was regarded as a substantial education philanthropist while keeping a low public profile in business. Wikipedia+1

Business-strategy summary — how Macaulay built his wealth

1. Specialize deeply in a single sector (energy).
   Rather than spreading broadly, First Reserve focused on energy (exploration & production, services, midstream, energy tech). That sector expertise let the firm source proprietary deals and add operational value. privateequitywire.co.uk+1

2. Buyouts and roll-ups in fragmented markets.
   First Reserve used buyout capital to acquire standalone, often family- or privately-held energy businesses and combine or scale them — a classic private-equity value-creation play in a fragmented industry. Forbes+1

3. Use of institutional capital & fundraising skill.
   Macaulay and partners raised large, specialized funds from institutional investors (pension funds, endowments), enabling big deals that produced outsized returns when oil or services markets were favorable. Forbes

4. Operational focus and management oversight.
   First Reserve emphasized hands-on oversight (board seats, management appointments, operational improvements) rather than passive minority investments — letting them actively re-shape portfolio companies. Forbes

5. Timing / commodity exposure risk management.
   Energy investing is cyclical. First Reserve benefited in booms but was exposed in downturns (e.g., post-2014 oil crash industry issues). The firm later diversified into related infrastructure and energy services to reduce pure commodity exposure. That strategic pivot was part of First Reserve’s later evolution. The Wall Street Journal+1

6. Low personal profile, high firm continuity.
   Macaulay stayed relatively private, while building a durable firm culture and succession plan that allowed First Reserve to keep fundraising and deploying capital through cycles. Private Equity International

Net effect: deep sector focus + buyout scale + institutional fundraising = concentrated opportunity to capture value in energy, which translated into Macaulay’s personal wealth (Forbes estimated ~$1.1B at time of death). Forbes+1

Short comparison: Macaulay vs other big energy billionaires

Below is a short, focused comparison showing how Macaulay’s path differed from other well-known energy billionaires (selected examples). Net worth figures change over time — I cite Forbes/Wikipedia profiles for the profiles below.

Quick takeaways:

• Macaulay = private-equity specialist: built a firm that raised capital from institutions and used buyouts/operational fixes to create value. Forbes+1

• Others (Hamm, Ambani, Koch, Kinder) are founders/operators or long-term private owners of large public/private energy companies; their wealth is more directly tied to company equity and operating results, rather than an institutional fund management model.
