[PAR] [TLE] Lotus Software [SEP] Lotus Software (called Lotus Development Corporation before its acquisition by IBM) was an American software company based in Massachusetts.  Lotus is most commonly known for the Lotus 1-2-3 spreadsheet application, the first feature-heavy, user-friendly, reliable and WYSIWYG-enabled product to become widely available in the early days of the IBM PC, when there was no graphical user interface.  Much later, in conjunction with Ray Ozzie's Iris Associates, Lotus also released a groupware and email system, Lotus Notes.  IBM purchased the company in 1995 for US$3.5 billion, primarily to acquire Lotus Notes and to establish a presence in the increasingly important client–server computing segment, which was rapidly making host-based products such as IBM's OfficeVision obsolete. [PAR] [TLE] Perkins Estate [SEP] The Perkins Estate is a historic estate at 450 Warren Street in Brookline, Massachusetts.  The property was part of the summer estate of the Cabot family, originally belonging to Thomas Handasyd Perkins; the present main mansion house was built in the 1850s to a plan by Edward C. Cabot for his sister-in-law, Elizabeth Perkins Cabot.  The grounds of the property were originally designed by Perkins, and subsequent generations maintained the grounds to a high degree.  In the 1980s it was owned by Mitch Kapor, founder of Lotus Software.
