# Coopers & Lybrand SMS
Coopers & Lybrand SMS was a management consultancy company that provided business solutions across various industries[1]. However, the company no longer exists as an independent entity. Coopers & Lybrand itself ceased to exist as a standalone firm in 1998 when it merged with Price Waterhouse to form PricewaterhouseCoopers (PwC)[4], one of the world's largest professional services networks.
The original Coopers & Lybrand operated as an accounting and consulting firm with deep expertise in financial audit, management consulting, and business advisory services. Before its merger, it had established itself as a major player in professional services, particularly in the UK, US, and Canada[4].
Coopers & Lybrand's history traces back to the 19th century through multiple founding lineages. William Cooper founded an accountancy practice in London in 1854, which became Cooper Brothers in 1861 when his three brothers joined[4]. Separately, Robert H. Montgomery, William M. Lybrand, Adam A. Ross Jr., and T. Edward Ross formed Lybrand, Ross Brothers and Montgomery in the United States in 1898[4].
These firms operated independently for decades before consolidating. In 1957, Cooper Brothers, Lybrand Ross Bros & Montgomery, and a Canadian firm (McDonald, Currie and Co.) agreed to adopt the unified name Coopers & Lybrand for international practice[4]. The three member firms formally changed their names to Coopers & Lybrand in 1973[4]. The firm expanded its capabilities in 1980 by acquiring Cork Gully, a leading UK insolvency specialist[4].
Coopers & Lybrand distinguished itself through several key strengths:
Coopers & Lybrand represented the consolidation trend in professional services during the latter half of the 20th century. As businesses grew more complex and international, accounting and consulting firms merged to create larger, more comprehensive service providers. The firm's evolution—from separate regional practices to a unified international brand—reflected the globalization of business and the increasing demand for integrated financial and management services.
By the 1990s, the professional services industry was consolidating further. Coopers & Lybrand's 1998 merger with Price Waterhouse created PwC[4], which emerged as one of the "Big Four" accounting and consulting firms that dominate the global professional services market today.
Coopers & Lybrand no longer exists as an independent entity, having been fully absorbed into PricewaterhouseCoopers. Its legacy lives on through PwC, which continues to operate the management consulting and audit services that Coopers & Lybrand pioneered. For those researching the company's history, understanding Coopers & Lybrand is essential to understanding how modern PwC was formed and the consolidation dynamics that shaped today's professional services industry.
