Desc	EDUCATION:WE WELCOMED 1,068,000 VISITORS TO THE ESTATE IN 2018, 350,000 OF WHICH WHERE STUDENTS WHO VISITED FROM ALL 50 OF THE UNITED STATES AND AROUND THE WORLD. WE REMAINED THE MOST POPULAR HISTORIC ESTATE IN AMERICA, AND REACHED EVEN MORE INDIVIDUALS THROUGH OUR ONLINE PRESENCE.IT WAS A NOTABLE YEAR FOR VISITS BY NEWSMAKERS AND LUMINARIES. ON APRIL 23, PRESIDENT DONALD TRUMP AND FIRST LADY MELANIA TRUMP HOSTED THEIR FRENCH COUNTERPARTS, EMMANUEL AND BRIGITTE MACRON, AT MOUNT VERNON FOR AN INTIMATE DINNER. GEORGE WASHINGTON'S RECONSTRUCTED DISTILLERY SERVED AS THE BACKDROP FOR THE JUNE 19 SIGNINGOF THE U.S. PATENT AND TRADEMARK OFFICE'S 10 MILLIONTH PATENT, AN EVENT ATTENDED BY SECRETARY OF COMMERCE WILBUR ROSS, USPTO DIRECTOR, ANDREI LANCU, AND OTHER DIGNITARIES. SECRETARY OF DEFENSE JAMES MATTIS BROUGHT CHINA DEFENSE MINISTER WEI FENGHE TO MOUNT VERNON ON NOVEMBER 8 AS PART OF AN OFFICIAL VISIT. THESE NOTEWORTHY GUESTS JOIN THE CONSTELLATION OF GOVERNMENT AND MILITARY FIGURES WHO HAVE TRAVELED TO THE HOME OF GEORGE WASHINGTON OVER THE YEARS FOR BOTH FORMAL GATHERINGS AND PERSONAL VISITS.WE CELEBRATED THE 286TH ANNIVERSARY OF OUR FIRST PRESIDENT'S BIRTH IN FEBRUARY BY UNVEILING A POWERFUL NEW ATTRACTION, BE WASHINGTON: IT'S YOUR TURN TO LEAD. LOCATED IN THE MUSEUM AND EDUCATION CENTER, THIS FIRST-PERSON INTERACTIVE EXPERIENCE PUTS GUESTS INSIDE THE MIND OF THE COMMANDER IN CHIEF AND PRESIDENT AT FOUR CHALLENGING MOMENTS IN HISTORY. PARTICIPANTS RECEIVE ADVICE FROM HISTORICAL FIGURES AND, ULTIMATELY, CHOOSE A COURSE OF ACTION. TO EXPAND ON THE IMPACT OF THIS POWERFUL NEW EXPERIENCE, WE LAUNCHED AN ONLINE VERSION OF THE GAME DESIGNED FOR USE IN CLASSROOMS. IN ITS FIRST YEAR, MORE THAN 130,000 PEOPLE ACCESSED THE BE WASHINGTON PLATFORM IN PERSON OR ONLINE. WE WERE HONORED TO RECEIVE AN INTERNATIONAL HONOR, THE THEA AWARD OF OUTSTANDING ACHIEVEMENT, FROM THE THEMED ENTERTAINMENT ASSOCIATION, AND ALSO TOOK HOME TOP HONORS AT THE SOUTHEASTERN MUSEUM CONFERENCE TECHNOLOGY COMPETITION.OUR LIVESTOCK PROGRAM HAS SERVED AS A "BEST-OF-BREED" EXAMPLE TO SIMILAR VENTURES AT OTHER HISTORIC SITES. RECOGNIZING THE POWERFUL ROLE THAT ANIMALS PLAY IN TELLING GEORGE WASHINGTON'S STORY, IN 2018 WE COMMENCED THE CONSTRUCTION OF A NEW LIVESTOCK FACILITY TO HOUSE THIS AWARD-WINNING PROGRAM. THE NEW BUILDING INCLUDES VETERINARY MEDICAL CARE FACILITIES, GROOMING CAPABILITIES, AND ADDITIONAL SPACE TO SHELTER THE ANIMALS DURING EXTREME WEATHER. CONSTRUCTION WILL BE COMPLETED IN 2019.FOR MORE THAN 60 YEARSSINCE MRS. FRANCES PAYNE BOLTON, VICE REGENT FROM OHIO, PURCHASED 485 ACRES OF LAND ON THE MARYLAND SHORELINE TO STOP THE CONSTRUCTION OF AN OIL REFINERYTHE MOUNT VERNON LADIES' ASSOCIATION HAS WORKED TIRELESSLY WITH PARTNERS ON BOTH SIDES OF THE POTOMAC RIVER TO PROTECT THE RURAL LANDSCAPE IN MOUNT VERNON'S VIEW SHED FROM OVERDEVELOPMENT. THIS EFFORT WAS TESTED AGAIN IN 2018 AS WE JOINED FORCES WITH LIKE-MINDED ORGANIZATIONS TO SUCCESSFULLY STOP THE CONSTRUCTION OF A NATURAL GAS COMPRESSOR STATION THAT MIGHT HAVE UNDERMINED THESE ACHIEVEMENTS. IN THE FIVE YEARS SINCE ITS OPENING, THE LIBRARY HAS DELIVERED A PROFOUND IMPACT ON SCHOLARS, EDUCATORS, AND LEADERS IN MYRIAD PROFESSIONS. TO MARK THAT ANNIVERSARY, WE HOSTED A SERIES OF EVENTS, INCLUDING A PRESENTATION BY THE LIBRARY'S NEW EXECUTIVE DIRECTOR, DR. KEVIN BUTTERFIELD, AND A VIRTUAL EDUCATION PROGRAM CREATED IN PARTNERSHIP WITH THE HARRY S. TRUMAN PRESIDENTIAL LIBRARY IN INDEPENDENCE, MISSOURI. OUR FOUNDING DEBATES PROGRAM, SPONSORED BY THE AMMERMAN FAMILY FOUNDATION TO HONOR JAMES C. REES, COMMEMORATED THE ANNIVERSARY WITH PRESENTATIONS BY NOTABLE HISTORIANS AND JOURNALISTS WHO EXPLORED THE THEME, "HISTORY, MEMORY, IDENTITY: WHAT IT MEANS TO BE AN AMERICAN." HIGHLIGHTING RESEARCH AND SCHOLARSHIP ACROSS THE ESTATE, THE LIBRARY ALSO FACILITATED THE PUBLICATION OF A NEW BOOK, STEWARDS OF MEMORY: THE PAST, PRESENT, AND FUTURE OF HISTORIC PRESERVATION AT GEORGE WASHINGTON'S MOUNT VERNON, EDITED BY CAROL BORCHERT CADOU, FORMER SENIOR VICE PRESIDENT FOR HISTORIC PRESERVATION AND COLLECTIONS, WITH LUKE J. PECORARO, FORMER DIRECTOR OF ARCHAEOLOGY, AND THOMAS REINHART, DIRECTOR OF PRESERVATION.OUR PROGRAMS, EVENTS, AND OUTREACH ARE DESIGNED TO BUILD CONNECTIONS WITH TODAY'S VISITORS. THUS, IN A NOD TO POPULAR INTEREST IN HEMP CULTIVATION, WE WORKED IN PARTNERSHIP WITH THE INDUSTRIAL HEMP RESEARCH PROGRAM AT THE UNIVERSITY OF VIRGINIA TO PLANT THE CROP IN OUR FIELDS FOR THE FIRST TIME SINCE WASHINGTON'S LIFETIME. THE HEMP'S HARVEST GARNERED WIDESPREAD MEDIA ATTENTION AND YIELDED A CROP DESTINED FOR USE IN ON-SITE TEXTILE DEMONSTRATIONS. WHEN THE ACCLAIMED MUSICAL HAMILTON APPEARED AT THE NEARBY KENNEDY CENTER DURING THE SUMMER MONTHS, WE MOUNTED A TEMPORARY EXHIBITION SHOWCASING HAMILTON-RELATED OBJECTS AND DOCUMENTS. IN JUNE, A PORTION OF THE CAST TRAVELED TO MOUNT VERNON FOR A SPECIAL TOUR OF THE ESTATE AND TO RECORD AN EPISODE OF OUR PODCAST.WASHINGTON'S ROLE AS AN ENTERPRISING SPIRITS MAKER CONTINUES TO DELIGHT VISITORS TO HIS RECONSTRUCTED DISTILLERY. THIS YEAR, WE ADDED A NEW TWIST TO THE STORY, CRAFTING THE FIRST BATCH OF RUM IN THE DISTILLERY'S TWELVE-YEAR HISTORY. ALTHOUGH WASHINGTON NEVER MADE RUM IN HIS DISTILLERY, THE SPIRIT WAS CERTAINLY PART OF THE CULTURE AT MOUNT VERNON, PARTICULARLY BEFORE THE AMERICAN REVOLUTION. IN ANOTHER NEW DISTILLING VENTURE WE ALSO PRODUCED BOURBON FOR THE FIRST TIME. FOR THIS PROJECT, THEY DREW UPON WASHINGTON'S RECORDS FROM 1797, IN WHICH HE LAMENTED THAT THERE WAS NOT ENOUGH RYE GRAIN ON HAND TO PRODUCE WHISKEY, FORCING HIM TO RELY ON CORN AND WHEAT INSTEAD. THE BOURBON WILL BE AGED FOR A MINIMUM OF FOUR YEARS. WHILE EXPERIMENTING WITH THESE SPIRITS, THE DISTILLERY CONTINUES TO PERFECT ITS SIGNATURE PRODUCT, GEORGE WASHINGTON'S RYE WHISKEY, WHICH RECENTLY EARNED A SILVER MEDAL AT THE AMERICAN CRAFT SPIRITS ASSOCIATION AWARDS.

Desc	HISTORIC PRESERVATION AND COLLECTIONS:AS PART OF A COMPREHENSIVE PLAN TO RESTORE EACH ROOM OF THE MANSION TO THE MOST ACCURATE POSSIBLE REPRESENTATION OF ITS 1799 APPEARANCE, WE FOCUSED OUR ATTENTION IN 2018 ON THE FRONT PARLOR. TO INFORM THE PROJECT, THE ARCHITECTURAL AND CURATORIAL TEAMS PORED OVER A RICH COLLECTION OF PRIMARY SOURCES, INCLUDING WASHINGTON'S PAPERS, DOCUMENTS FROM HIS HEIRS, AND THE ARCHIVES OF THE MOUNT VERNON LADIES' ASSOCIATION. FROM THERE, THE ARCHITECTURAL TEAM LAUNCHED AN IN-DEPTH PHYSICAL INVESTIGATION INTO THE SPACE, ASSESSING EVERY ELEMENT FROM THE PANELING VISIBLE TODAY TO THE PLASTER, LATH, AND FRAMING MEMBERS DATING TO THE 1730'S AND 1740'S. WORK ON THE WOOD-PANELED WALLS LED TO A REMARKABLE DISCOVERY: AN EARLIER GENERATION OF PANELING COMPOSED OF MOLDED AND PAINTED PLASTERA TECHNIQUE RESERVED FOR THE FINEST ROOMS IN THE MOST ELITE HOMES IN THE CHESAPEAKE REGION. THE ROOM'S EXISTING WOOD PANELS, INSTALLED IN THE LATE 1750'S TO EARLY 1760'S, HAD WARPED UNDER THE STRAINS OF WEATHER AND TIME AND WERE SUCCESSFULLY REHYDRATED USING INNOVATIVE PRESERVATION METHODS. IN PREPARATION FOR THE ROOM'S REINSTALLATION AND UNVEILING IN EARLY 2019, THE CURATORIAL TEAM WORKED BEHIND THE SCENES TO RE-CREATE THE ROOM'S DOCUMENTED FURNISHINGS: A SOFA AND EIGHT CHAIRS UPHOLSTERED IN SILK AND WOOL DAMASK DYED A STRIKING SAXON BLUEA HIGHLY FASHIONABLE HUE INVENTED IN THE 1750'S.NEW RESEARCH AND INSIGHTS ALSO INSPIRED CHANGES TO THE MANSION'S CENTRAL PASSAGE IN 2018. EARLY IN THE YEAR, THE SPACE WAS RETURNED TO A MORE AUTHENTIC REPRESENTATION OF ITS 1799 APPEARANCE, TRADING ITS DARK, WOOD-GRAINED PANEL WALLS FOR A LIGHTER BEIGE COLOR. ORIGINALLY FINISHED WITH PANELING IN THE LATE 1750'S, THE CENTRAL PASSAGE WAS ROUTINELY UPDATED WITH THE MOST FASHIONABLE PAINT COLORS DURING WASHINGTON'S LIFETIMEENDING AT THE TIME OF HIS DEATH WITH THE CURRENT COLOR, KNOWN, IN THAT ERA, AS "STONE." MICROSCOPIC PAINT ANALYSIS CONFIRMED THAT THE TYPE OF WOOD-GRAINED TREATMENT ON VIEW SINCE 1981 WAS NOT IN PLACE UNTIL AFTER WASHINGTON'S DEATH. THE CENTRAL PASSAGE'S REPAINTING PROVIDED A PRIME OPPORTUNITY FOR ATTENTION TO ONE OF OUR MOST TREASURED OBJECTS, THE KEY TO THE BASTILLE, PRESENTED IN ITS ORIGINAL GILT DISPLAY CASE. THE CASE IS A RARE, POSSIBLY UNIQUE EXAMPLE OF 18TH-CENTURY CRAFTSMANSHIP, BELIEVED TO HAVE BEEN CUSTOM DESIGNED FOR PRESIDENT WASHINGTON BY A PHILADELPHIA CARVER. ALTHOUGH THE CASE'S DELICATE WOOD FRAME AND FRAGILE GLASS PANES REMAINED REMARKABLY INTACT, OTHER ELEMENTS REQUIRED RESTORATION, SUCH AS THE GILT EXTERIOR AND A MISSING ORNAMENTAL CENTRAL DROP, WHICH WAS FORTUNATELY DOCUMENTED IN AN EARLY PUBLICATION. NEW METAL MOUNTS WERE ALSO CRAFTED TO SUPPORT BOTH THE CASE ITSELF AND THE KEY INSIDE.OUR PROFESSIONAL STAFF ALSO LAUNCHED SIGNIFICANT PROJECTS BEHIND THE SCENES AND BELOW THE FLOORBOARDS OF THE MANSION, ENSURING THE HOME'S LONG-TERM SUSTAINABILITY. AS A KEY STEP IN THIS PROCESS, THE ARCHAEOLOGY TEAM CONDUCTED AN UNUSUAL EXCAVATION INSIDE THE MANSION BASEMENT, UNCOVERING FASCINATING EVIDENCE OF EARLY DRAINS AND WALL FOUNDATIONS GUIDING US TO A MORE DETAILED AND ACCURATE UNDERSTANDING OF HOW AND WHEN THE CELLAR EVOLVED. OUTSIDE THE MANSION, WE LAID THE GROUNDWORK FOR THE RESTORATION OF THE EAST SLOPE, WHERE A HEAVY STORM IN 2017 HAD DAMAGED A SECTION OF BRICK WALL AND SURROUNDING HILLSIDE. WORKING WITH LEADING STRUCTURAL AND GEOTECHNICAL ENGINEERING EXPERTS, WE CONDUCTED A COMPREHENSIVE ASSESSMENT TO IDENTIFY SOLUTIONS FOR A LANDSCAPE PROBLEM THAT HAS VEXED MOUNT VERNON SINCE WASHINGTON'S LIFETIME. SITE WORK TO IMPROVE DRAINAGE SYSTEMS AND REBUILD THE WALL WILL BEGIN IN EARLY 2020.TO ENSURE ITS SAFETY IN THE EVENT OF A FIRE, WE COMMENCED WORK ON THE INSTALLATION OF A NEW STATE-OF-THE-ART FIRE SUPPRESSION SYSTEM INSIDE THE MANSION, WHICH WILL BE COMPLETED IN LATE 2019. THE SYSTEM WILL BE EXPANDED TO INCLUDE THE ORIGINAL OUTBUILDINGS ONCE ADDITIONAL FUNDING HAS BEEN SECURED.	Desc
