On June 29, 1763, Dr. John Tyler was born in Prince George's County. He is credited as the first doctor in America to surgically treat cataracts. He died October 15, 1841, in Frederick. He also built Spite House on West Church Street in Frederick to keep city fathers from extending Record Street through to West Patrick Street. He said that the horse and wagon traffic beside his home and office (now the residence of the rector of All Saints Episcopal Church) would disturb his delicate surgery. On June 29, 1792, a deed was signed for a lot on West Church Street owned by Lenox Martin to a group of trustees for the first Methodist Church in Frederick. On June 29, 1819, the Reformed Church of Middletown dedicated its new sanctuary. This was the fourth church of this congregation. On June 29, 1829, snow fell in the Middletown area according to Jacob Englebrecht's diary. On June 29, 1859, The Examiner announced that C. S. Williams, of Cincinnati, was about to publish a Frederick City Directory. Copies of this volume, the first of its kind published about Frederick, are available at both The C. Burr Artz Library and at the Historical Society of Frederick County. On June 29, 1878, Herbert Thompson resigned as principal of The Charlotte Hall School. Shortly afterward, he and his wife, Lady Ellen Thompson, opened Glenellen Academy in Ijamsville. It closed in 1888. On June 29, 1895, Caroline E. Davis became the first graduate of The Notre Dame Academy in Libertytown. The school, which opened in 1891, closed its doors at the end of the 1970 school year. On June 29, 1948, the William R. Diggs pool at Mullinex Park was dedicated with more than 300 people in attendance. Holmes D.
