Founding Story

In 1885, Albert Butz patented the 'damper flapper', a device that opened and closed a coal furnace's damper automatically as room temperature changed, and formed a company to sell it. Separately, Mark C. Honeywell founded Honeywell Heating Specialty Company in Wabash, Indiana, in 1906. The two lineages merged in 1927 as Minneapolis-Honeywell Regulator Company, which is why the modern company traces its automation roots to a thermostat.

Albert Butz

Co-founder 1885

Background

Albert Butz was a Swiss immigrant to the United States who worked as a mechanical inventor on early automatic control devices.

Role at Honeywell Technologies

Albert Butz was a Swiss-born American inventor whose work is the origin of Honeywell. In 1885 he patented the 'damper flapper', an early automatic thermostat mechanism for controlling indoor temperature. He founded the Butz Thermo-Electric Regulator Company to sell it. His patents and that early business were the starting point of the automated controls company that later became Honeywell.

Albert Butz was born in 1849 in Switzerland.

Butz was born in Switzerland in 1849 and died in 1905. His Butz Thermo-electric Regulator Company became Honeywell through a series of reorganisations, name changes and mergers.

Mark C. Honeywell

Co-founder 1906

Background

Mark C. Honeywell worked in heating technology as a contractor before he started his own company, and later ran the business through its 1927 merger.

Role at Honeywell Technologies

Mark C. Honeywell was an American industrialist who gave the company its name. He was a heating contractor, and in 1906 he founded the Honeywell Heating Specialty Company to make hot water heat generators. In 1927 he merged it with the Minneapolis Heat Regulator Company, the successor to Albert Butz's original firm. He led the combined Minneapolis-Honeywell Regulator Company, which grew through acquisitions into aerospace, building technologies and industrial automation.

Mark C. Honeywell was born in 1874 in Florida. Education: Eastman Business College.

Vimal Kapur

Chairman and Chief Executive Officer

2023 – Present

Kapur is notable among major American industrial CEOs for reaching the top of a Fortune 500 company without a MBA or an US university degree. He has said Honeywell was already preparing the three-way breakup roughly a year before activist investor Elliott Management publicly called for it in November 2024, and by mid-2026 he had completed both the Solstice spin-off (October 2025) and the Aerospace spin-off (June 2026), the most significant restructuring in the company's history.

Darius Adamczyk

Former Chairman and Chief Executive Officer

2017 – 2023

Adamczyk oversaw $7.5 billion in strategic divestitures to modernize Honeywell's portfolio and built the software-and-services strategy that his successor, Vimal Kapur, used as the technical foundation for the 2025-2026 three-way breakup -- the Forge platform remained central to Honeywell Technologies' recurring-revenue pitch after the Aerospace and Solstice separations.

David M. Cote

Chairman and CEO

2002 – 2017

Under Cote Honeywell grew its market value and margins, and he handed the chief executive role to Darius Adamczyk in 2017.

Michael R. Bonsignore

Chairman and Chief Executive Officer

1999 – 2001

He agreed in 2000 to sell the company to General Electric. European regulators blocked the deal in July 2001 and he was replaced by Lawrence Bossidy.

Who Founded Honeywell? FAQ

Who were the historical inventors and founders behind Honeywell's origins?

Honeywell traces its corporate origins to two foundational innovators: Albert Butz, who invented the automatic furnace damper regulator (thermostat) in 1885 in Minneapolis, and Mark C. Honeywell, who founded the Honeywell Heating Specialty Company in 1906 in Wabash, Indiana.

What was Albert Butz's invention of the 'damper flapper' in 1885?

In 1885, Albert Butz patented the 'damper flapper,' an automatic temperature control system that used a spring-wound motor and thermostat to automatically open and close furnace drafts when room temperatures changed, establishing the foundation for modern heating control systems.

How did W.R. Sweatt build the Electric Heat Regulator Company?

William Richard Sweatt acquired control of the consolidated descendant of Butz's patents, renaming it the Electric Heat Regulator Company. Sweatt designed the well-known 'Jewell' thermostat with an integrated clock mechanism, establishing the commercial mass market for residential temperature automation.

How did the 1927 merger create the Minneapolis-Honeywell Regulator Company?

In 1927, Mark Honeywell's Honeywell Heating Specialty Company (a leader in hot water heating systems) merged with W.R. Sweatt's Electric Heat Regulator Company to form the Minneapolis-Honeywell Regulator Company, combining the leading patents and distribution networks in temperature automation.

What was Mark C. Honeywell's role in the combined enterprise?

Mark C. Honeywell served as the first president of the merged Minneapolis-Honeywell Regulator Company from 1927 to 1935, and later as Chairman of the Board. His engineering expertise in water heating systems and leadership established the company as an industrial manufacturing leader.

How did the Sweatt family steer Honeywell across three generations?

The Sweatt family provided decades of leadership: W.R. Sweatt served as original chairman, his son Harold W. Sweatt led the company through large World War II military aviation controls manufacturing and early computing, and his son Charles Sweatt served as vice chairman, shaping Honeywell's mid-century expansion.

How did AlliedSignal's acquisition of Honeywell in 1999 form the modern corporation?

In 1999, aerospace and automotive giant AlliedSignal (led by Larry Bossidy) merged with Honeywell Inc. for $14 billion. Although AlliedSignal was the acquiring entity and provided the management backbone, the combined corporation retained the globally renowned Honeywell brand name and relocated to AlliedSignal's New Jersey headquarters.

What historical values of the original founders remain integral to Honeywell today?

The founding principles established by Butz, Honeywell, and Sweatt, technological invention, automated energy efficiency, mission-critical precision controls, and rigorous engineering quality, continue to drive Honeywell's modern innovations across aerospace, automation, and sustainable energy.

Who founded Honeywell?

While Mark Honeywell gave the company its name, the true technical foundation belongs to Albert Butz. In 1885, Butz invented the "damper flapper," a massive predecessor to the modern thermostat that automatically regulated coal furnaces. Honeywell bought Butz's patents, setting the foundation for 100 years of automation dominance.
