Gerrardus Wynkoop (September 30, 1732 – June 18, 1812)[1] was a member of the Pennsylvania House of Representatives from Bucks County and served as speaker of the House in 1793.
Wynkoop won elections as a representative to the Assembly in the following years. Names listed with him are the others from Bucks County who won. (Note: The spelling of the last name of the politician whose first name is Valentine is listed exactly as it is referenced in the original sources. The correct spelling is unknown.)
On December 22, 1786, at the resignation of Thomas Mifflin as speaker of the Assembly, Wynkoop was elected speaker. He received forty-five votes and was escorted to the chair by Daniel Clymer. The oath was administered by a Mr. Evans. By December 26, 1786, around noon, Wynkoop resigned as speaker and Mifflin was re-elected.
Before the Pennsylvania Constitution was adopted in 1790, the state had a unicameral legislature. Wynkoop was a member of that legislature. On Saturday, September 4, 1790, the Assembly made an address to the people of the state of Pennsylvania, indicating the body was resigning from power due to concerns that their authority had ceased at the adoption of the new state Constitution. The speaker of the Assembly, Richard Peters, declined to be seated. Wynkoop was instead seated in the speaker's chair for this address.
Wynkoop, along with Jacob Hiltheimer, escorted Richard Peters to the speaker's chair after his election. Peters was the final speaker of the unicameral general assembly.
According to Wynkoop's obituary, he served nineteen years in the Assembly. It also notes that he served as speaker for several of those years. However, he was elected Bucks County Assessor in 1771 and 1773, which puts this claim in dispute. It could be correct if the writer meant to include both the State Assembly and the House of Representatives (Wynkoop lost the election in 1794), assuming Wynkoop won his first election to the Assembly in 1775.
Wynkoop served as Speaker of the Pennsylvania House of Representatives in 1793.
Assessor for Bucks County
Presidential Elector
Wynkoop chaired a meeting on September 20, 1792, in Lancaster to select candidates for Congressional seats and Presidential electors. The list of electors does not include his name. However, an article dated August 27, 1792, does list his name as a Presidential elector.
According to Wynkoop's obituary, he showed great care for widows and orphans. He was in the communion of the Dutch Reformed Church for over forty years.
