Definition
The presiding officer of a deliberative or organized body. The term applies across a wide range of institutional settings:
(1) In legislative and governmental contexts: the officer who presides over a deliberative assembly, convention, public meeting, or legislative body. In parliamentary usage, the chairman maintains order, recognizes speakers, and manages the conduct of business.
(2) In corporate contexts: the presiding officer of a board of directors. The chairman of the board is distinct from the chief executive officer (CEO) and from the president of a corporation, though these roles are sometimes combined. The chairman typically presides at board meetings, sets the agenda in coordination with management, and may represent the board in formal communications.
(3) In committee contexts: the presiding member of a committee, whether legislative, administrative, or organizational. The committee chairman generally controls the agenda, recognizes members, and may have procedural authority over whether matters advance to the full body.
Common Language
Modern common usage (Wiktionary): A person presiding over a meeting; the head of a corporate or governmental board of directors, a committee, or other formal entity. (A secondary historical meaning — a person employed to carry a sedan chair — is now obsolete.)
Historical common usage (Webster's 1913): The presiding officer of a committee, or of a public or private meeting, or of any organized body. Webster's also preserved the sedan chair carrier meaning as a live usage.
The legal meaning of chairman tracks the common meaning closely for general presiding functions, but diverges in corporate law, where the chairman of the board carries a defined role with fiduciary responsibilities, governance authority, and — depending on the jurisdiction and the entity's governing documents — specific powers distinct from other officers. A researcher who encounters "chairman" in common historical usage should not assume it carries the structured legal weight the term bears in modern corporate governance.
Recognized Forms
/SUBTYPES
Chairman of the Board: In corporate law, the presiding officer of the board of directors. Duties and authority are typically defined by the corporation's bylaws. May be executive (an inside chairman, often combined with CEO) or non-executive (an independent chairman who does not serve in a management role).
Chairman of a Committee: The presiding member of a legislative or organizational committee. In legislative bodies, committee chairmanships confer significant procedural power, including control over whether legislation is scheduled for a vote.
Chairman of a Public Meeting: A purely presiding function at a public assembly or convention, without the ongoing governance authority that attaches to a board or legislative chairmanship.
Why It Matters in Research
The principal research challenge with "chairman" is that the term carries very different legal weight depending on context. In a nineteenth-century document, "chairman" at a public meeting is a temporary presiding function. In a twentieth-century corporate instrument, "chairman of the board" is a defined office with fiduciary dimensions. Researchers working across eras or across document types should not treat these uses as equivalent.
In corporate governance research, the distinction between an executive and non-executive chairman has become increasingly significant, particularly in securities regulation and corporate accountability debates. Historical documents will not use this vocabulary; the distinction must be inferred from the structure described.
In legislative history research, committee chairmen appear frequently in congressional and state legislative records. The procedural powers of a committee chairman — especially gatekeeping authority over legislation — are relevant to understanding why certain bills advanced or died, but those powers are governed by chamber rules, not by statute, and vary across bodies and eras.
Anderson's Dictionary of Law cross-references DESCRIPTIO PERSONAE rather than defining the term directly, suggesting that in some historical legal contexts, "chairman" appeared primarily as a descriptive identifier of a party rather than as a term of art requiring definition. Researchers encountering "chairman" in pleadings or party designations should consider this use.
Gender-neutral equivalents — "chair" and "chairperson" — appear in modern statutes, bylaws, and organizational documents. Historical sources will consistently use "chairman" regardless of the officeholder's gender. When searching historical records, do not assume "chair" or "chairperson" as alternative search terms will capture period usage.
Historical Dictionary Support
Black's Law Dictionary (both the first and second editions) defines chairman identically: the presiding officer of an assembly, public meeting, convention, deliberative or legislative body, board of directors, or committee. The definition is purely functional and makes no distinction between the corporate and non-corporate settings.
Rapalje & Lawrence is the most analytically useful of the historical sources, drawing an explicit distinction between the presiding officer of a deliberative body (sense 1) and the president or senior member of a committee (sense 2). This is the only historical source to disaggregate the term. Rapalje & Lawrence also specifically names the speaker of a house of assembly and the presiding member of a board of directors as examples, making it useful for researchers working in both legislative and corporate contexts.
Anderson's Dictionary of Law's cross-reference to DESCRIPTIO PERSONAE is an outlier and reflects a specific legal use — the term appearing as a description of a person in a legal instrument — rather than a substantive definition. This entry is of limited value for understanding the term's operative legal meaning but alerts researchers to its appearance in pleadings and formal instruments as a descriptive tag.
No historical dictionary source addresses the governance significance of the chairman of the board in the modern corporate sense, reflecting how much corporate governance has evolved since these sources were compiled. The modern distinction between executive and non-executive chairmen, or the independence standards imposed by stock exchange listing rules, is entirely absent from historical legal dictionaries.
Jurisdictional Note
In U.S. corporate law, the powers and duties of the chairman of the board are defined by state corporation statutes and, more specifically, by the corporation's own bylaws; there is no uniform federal standard. Delaware corporate law, which governs the largest share of U.S. public companies, gives considerable latitude to bylaws in structuring the chairman's role. Researchers working with foreign corporations should note that "chairman" in UK and Commonwealth usage often carries specific statutory or regulatory meaning under company law, which may differ materially from U.S. usage.
