Harav Yaakov Viderevitch (5595-5671) was a chossid of the Tzemach Tzedek and the Rebbe Maharash. A yoshev in Lubavitch by the Tzemach Tzedek, he was later chosen to serve as the publisher of the Tzemach Tzedek’s teshuvos. He served as the Rov of Kopishok and later as the Rov of the Chassidim in Moscow, and he corresponded with the Rebbe Maharash on matters of halachah.
In 5653, the Jews were expelled from Moscow, and R. Viderevitch moved to America where he was appointed as the Rov of a union of "Nusach Sefard" shuls. He was one of the leading Rabbonim in America at the time. R. Viderevitch was famous for his sharp sense of humor and witticisms, and many witty stories are told about him. A number of teshuvos written by R. Viderevitch are extant in manuscript.
The Frierdiker Rebbe related:
While in Moscow, R. Viderevitch was once taking a walk with Mr. Zev Wissotzky, founder of the tea company and Rosh Hakahal. R. Viderevitch respected Wissotzky for his incredible tzedaka, but he was displeased with how he ran the community, by handing it over to modern elements.
As they strolled on the Chistye Prudy boulevard, they noticed young rich Jews walking their well-adorned dogs, big and small, in the latest style. Those with small dogs could lead the dogs, but those walking big dogs, it was the dog leading the owner.
Mr. Wissotzky turned to R. Viderevitch, "Look at the new style of these young people – to love and befriend dogs?! They have found new friends to walk with! What do you say to that?"
"What should I say?" R. Viderevitch replied, "They're creating a new society in which people are led by dogs. And the richer one is, the bigger the dog..."

When R. Viderevitch settled in America in 5653 (1893), he had a sign hanging outside his home naming him the "Chief Rabbi of America." When someone questioned who appointed him to this position, he answered wittily, "The sign painter!" When asked why he chose this title, he replied that they will need to come together from all across the country to demote him.
