The notice appeared on April 2, 1855. Charge Of Taking Daguerreotypes On Sunday. M. W. Lockwood, a daguerreotypist, doing business at the corner of Eighth avenue and Fourteenth street, was arrested yesterday by Captain Ackerman, of the Ninth ward police, charged with having taken daguerreotype likenesses on Sunday, contrary to a city ordinance. The accused was arrested on the complaint of officer Winars, who, it is alleged, entered Lockwood’s place and got his likeness taken, as also did his brother and several others who were present. The artist, along with his show case, which was standing on the sidewalk, was conveyed before Justice Davison, at the Jefferson Market Police Court, where a fine of one dollar was imposed upon the offender.
