I’ve been researching Hollar and his work and thought I’d share what I have learned so far. I thought I posted this earlier but sometimes my browser lies to me.
William H. Hollar was a vault designer based in Philadelphia. He was innovative, using new features such as an electric timelock winder which allowed increasing the set time remotely without opening the door. This was thought to be useful in an era where riots or fire could disrupt access to a vault, and automatic unlocking would be a bad idea (the pressure bars would still hold the door tightly closed in case of a fire or flood but would be no defense against bad guys). He also seemed to prefer automatic bolt motors over combination locks.
Known examples appear well made with a very sturdy appearance. It also seems that Hollar did not actually manufacture vaults or doors and supervised/subcontracted this work to several other firms (whose names were sometimes mentioned on the plaques affixed to the doors, including Hall’s, Miller, Damon, Mosler, Carnegie Steel, and others).
1873: He was a traveling salesman for the Hall Safe & Lock Company for many years (see biography, below).
1881: “He organized, in 1881, Hollar’s Safe & Lock Company at York, Pennsylvania, for the purpose of manufacturing vaults, safes and locks, and, after placing this company in a satisfactory condition, he sold his interests to the company afterwards known as the York Safe & Lock Company” (see biography, below).
1890: A very early mention of the “Hollar Lock Inspection and Guarantee Co” was in the Annual Report of the Comptroller of the State of New York, (http://books.google.com/books?id=ZiwzAQAAMAAJ&pg=PA191&dq=%22hollar+lock+inspection%22&hl=en&sa=X&ei=hNiBUY_cKq_8yAGgsIB4&ved=0CE8Q6AEwBjgU#v=onepage&q=%22hollar%20lock%20inspection%22&f=false).
1891: The “Hollar Lock Inspection Company” was listed in the Boston Almanac and Business Directory at 220 Devonshire, Boston (http://books.google.com/books?id=eYEBAAAAYAAJ&pg=PA343&dq=hollar+lock+inspection&hl=en&sa=X&ei=saGBUa69GKf1ygGNgoHoCw&ved=0CE4Q6AEwBA#v=onepage&q=hollar%20lock%20inspection&f=false).
1892: “The Hollar Lock Inspection and Guaranty Company” was listed in an 1892 Philadelphia Securities directory with offices at 122 and 124 Times Building, Park Row, New York; and Philadelphia offices in the Drexel Building, room 735. The description is “Engineers and superintendents of vault and safe construction” with capital of $50,000. Officers were William H. Hollar, President; Rollin M. Morgan, Secretary; directors John J. Knox of New York, Benjamin B. Comegys of Philadelphia, William H. Hollar, Rollin M. Morgan, and Maus R. Vedder. Also listed in 1896 (http://books.google.com/books?id=tdIwAQAAMAAJ&pg=PA62&dq=hollar+lock+inspection&hl=en&sa=X&ei=saGBUa69GKf1ygGNgoHoCw&ved=0CFgQ6AEwBg#v=onepage&q=hollar%20lock%20inspection&f=false) though they may have spelled “Guaranty” incorrectly as “Guarantee”.
1898: an article in United States Investor alleges that Hollar was “unpopular among safe manufacturers” (http://books.google.com/books?id=kTxOAAAAYAAJ&pg=PA75&dq=hollar+lock+inspection&hl=en&sa=X&ei=nryBUbWdHYmEygGV1YGYBQ&ved=0CDIQ6AEwATgK#v=onepage&q=hollar%20lock%20inspection&f=false).
1902: an article in Electrical World and Engineer (http://books.google.com/books?id=hbZQAAAAYAAJ&pg=PA786&dq=%22hollar+lock+inspection%22&hl=en&sa=X&ei=GtmBUd_uH4rgyQHh0YHABw&ved=0CGAQ6AEwCTgU#v=onepage&q=%22hollar%20lock%20inspection%22&f=false) mentions the Farmers’ Deposit National Bank in Pittsburgh having a Hollar vault and the method of supplying DC power for the winding mechanism. The building was at 500 Wood Street but it was demolished in 1997 (http://en.wikipedia.org/wiki/Farmers_Bank_Building_(Pittsburgh), http://www.emporis.com/building/farmersbankbuilding-pittsburgh-pa-usa).
1904: the company address was 421 Chestnut, Philadelphia (Boyd’s Co-partnership and Residence Business Directory of Philadelphia City, http://books.google.com/books?id=R9MwAQAAMAAJ&q=hollar+lock+inspection&dq=hollar+lock+inspection&hl=en&sa=X&ei=ZsCBUenqIIz8yAH484C4Bg&ved=0CDoQ6AEwAzgK).
1905: The name was shortened to The Hollar Company on June 29, 1905 (http://books.google.com/books?id=yH44AAAAIAAJ&pg=PA93&dq=hollar+lock+inspection&hl=en&sa=X&ei=saGBUa69GKf1ygGNgoHoCw&ved=0CDwQ6AEwAQ#v=onepage&q=hollar%20lock%20inspection&f=false), listed at 60 Wall Road #1505 (1906, http://books.google.com/books?id=8cQpAAAAYAAJ&pg=PA332&dq=hollar+lock+inspection&hl=en&sa=X&ei=ELuBUbv7MeSMygHq7oDwCw&ved=0CC0Q6AEwADgK#v=onepage&q=hollar%20lock%20inspection&f=false).
1908: The Hollar Company designed vaults for the Safe Deposit Company of New York in the Singer Building (http://books.google.com/books?id=NKRPAAAAMAAJ&pg=PA112&lpg=PA112&dq=%22hollar+company%22+vault+-gadsden&source=bl&ots=kUbPEW7XZu&sig=cSFnTx1qbbntDcF7hWTZs1fQnJI&hl=en&sa=X&ei=QIeCUfeLG8i4yAHA3oHYCg&ved=0CDQQ6AEwAg#v=onepage&q=%22hollar%20company%22%20vault%20-gadsden&f=false) which was demolished in 1968.
Some biographical information on Hollar is in 1914’s “Encyclopedia of Pennsylvania Biography” at http://books.google.com/books?id=K-UsAAAAYAAJ&pg=RA5-PA198-IA1&lpg=RA5-PA198-IA1&dq=%22hollar+company%22+vault+-gadsden&source=bl&ots=qqgvKOFIQ_&sig=bDlBz4QhcVfJ5XxP18so9pv3Ero&hl=en&sa=X&ei=QIeCUfeLG8i4yAHA3oHYCg&ved=0CDYQ6AEwAw#v=onepage&q=%22hollar%20company%22%20vault%20-gadsden&f=false . He was born in Ohio on June 1, 1851. At age 13 his father died and he had to support his mother and three siblings working in machine shops. In 1873 he was a salesman for the Hall Safe & Lock Company. In 1881 he formed Hollar’s Safe & Lock Company which he later sold, and which became the York Safe & Lock Company. He married Laura L. Rankin in 1875, had three children, his wife died in 1883. He married Laura A. Traver in 1887. One of his children was named William H. Hollar, Jr.; that name appears on some of the very last Hollar patents. I don’t have a date of death for him, but his US patent 1,238,073 was filed in 1914 and by the time it was granted in 1917 he was deceased with his wife Laura as the executrix of his estate.
Some information on Hollar is in the book American Genius though it is focused on time locks used by Hollar.
