History

Early years

1952 political march by the International Ladies Garment Workers Union. Among their signs is "Repeal Hartley–Taft Act"

Attorneys Henry Seyfarth, Lee C. Shaw, and Owen Fairweather established Seyfarth Shaw in Chicago in 1945. All three attorneys met while associates at the firm of Pope & Ballard which originally focused on the area of labor law.

  • Henry Seyfarth (1908-1991) graduated from the University of Illinois in 1928 and two years later received his J.D. degree from the University of Chicago Law School. He served as an assistant state’s attorney in Cook County from 1930 to 1935 and as partner of the law firm Pope & Ballard from 1935 to 1945 before joining with Shaw and Fairweather to launch their own firm. While at Pope & Ballard, he, along with Shaw and Fairweather, represented corporate clients.
  • Lee Shaw (1913-1999) was born in Red Wing, Minnesota. He later enrolled at the University of Michigan where he played football as an offensive and defensive lineman alongside future President Gerald Ford. He later earned a J.D. degree from the University of Chicago in 1938. Following the passage of the of the Wagner Act in 1935, which established the rights of workers to bargain collectively, Pope & Ballard set out to create a specialty in the field of labor law, concentrating on representing corporate and management interests in labor relations. Shaw helped draft the Labor Management Relations Act of 1947, also known as the Taft-Hartley Act. He was named to the drafting panel after serving on the National War Labor Board, which was responsible for monitoring labor issues in World War II.
  • Owen Fairweather (1914-1987) earned his undergraduate degree from Dartmouth College in 1935 where he was a member of the Psi Upsilon Fraternity. He then graduated cum laude from the University of Chicago Law School in 1938. He served on the National War Labor Board in Washington, D.C., during World War II. In 1945, he and his two colleagues, Henry Seyfarth and Lee Shaw, left Pope & Ballard to form their own firm, taking their corporate clients with them. The Owen Fairweather Scholarship Fund at the University of Chicago Law School was established in 1987.

National and international expansion

By 1964, the firm was known as Seyfarth, Shaw, Fairweather & Geraldson, having incorporated the name of partner Ray Geraldson.

In 1971, the firm established a presence in Washington, D.C. and expanded into legislative and regulatory affairs.

After years of strikes, picketing, boycotts and solidarity actions in support of California farmworkers — such as the Delano grape strike and the Salad Bowl strike — the firm opened an office in Los Angeles in 1973, seeking to represent farmowners in labor negotiations against United Farm Workers. The struggle ultimately led to the enactment of the California Agricultural Labor Relations Act, which established the right to collective bargaining for farmworkers in that state.

The firm further expanded throughout the 1970s and 1980s, opening offices in New York City (1978) and San Francisco (1984).

In 1990, the firm opened its first international office in Brussels, Belgium in order to assist corporate clients in the European Economic Community. The firm further expanded through the 1990s, opening offices in Sacramento (1990), Houston (1995), Atlanta (1996).

In 1999, the firm established a Boston office after recruiting seven lawyers. The office expanded in 2001 after a merger with Boston-based firm Chappell White LLP.

Wanting to change the perception that it "only did employment law and only practiced in Chicago," the firm rebranded in 1999 and shortened its name to Seyfarth Shaw.

The Atlanta office expanded in 2000 when Atlanta-based law firm McCullough Sherrill was acquired, giving the firm a broader presence in the southeast. The acquisition added 40 attorneys and expanded capabilities in corporate, litigation, and commercial real estate.

The firm merged with fellow Chicago firm D’Ancona & Pflaum LLC in 2003 adding 60 attorneys, including 34 partners, to the firm's roster. The merger diversified and expanded practices areas including corporate, litigation, and real estate.

21st century

The firm further expanded internationally in the 2010s, opening offices in:

An acquisition of nearly two dozen attorneys from Atlanta-based Morris, Manning & Martin to the Atlanta office in 2025 expanded the firm’s national transactional footprint across middle market corporate, hospitality, real estate private equity, fund formation, and tax practices.

Amid geopolitical tensions and an exodus of American law firms from mainland China, the Shanghai office was closed in 2025.

In 2026, the New York-based boutique firm Mukasey Young dissolved to join Seyfarth. The trial-focused team expanded the firm’s capabilities in white collar defense, complex litigation, and health care regulatory matters.

Emphasis on legal innovation

Starting in 2004, managing partner J. Stephen Poor began encouraging the use of sophisticated management systems to drive efficiency as a way to modernize legal service delivery. The following year, Poor championed the launch of SeyfarthLean, a team of 15 project managers dedicated to applying lean principles to legal work. In 2008, the firm launched SeyfarthLean Consulting, which offered process improvement services to clients and their in-house legal departments.

The firm established a Legal Technology Innovations Office in 2012 to explore how software could enhance client-facing legal services. This initiative led to the creation of Seyfarth Labs in 2016, bringing together 21 lawyers and software engineers to develop new tools and platforms. Seyfarth Labs became one of the first innovation incubators launched within a law firm. Some of the projects launched by the Seyfarth Labs team includes automated contract and discovery templates, a real-time COVID-19 resource tracker, and digital intake tools supporting the transition to electric vehicles.

In 2017, Seyfarth partnered with software company Blue Prism to develop robotic process automation (RPA) solutions designed to handle repetitive tasks, freeing attorneys to focus on more strategic legal work.

The firm has been recognized for legal innovation and business process improvement. They were among the first to embrace Lean Six Sigma in legal project management, an initiative later profiled in a Harvard Law School case study.

In 2024, the firm invited its attorneys and professional staff to propose solutions to pressing legal or business issues. The inaugural competition generated 59 submissions, including an AI-assisted pre-bill review tool, an AI-enhanced playbook for client and deal teams, and contextualized training modules for associates. The winning project was later developed into a practical tool by Seyfarth Labs. A second internal competition was held in 2025.
